Instructions for using foam adhesive 1. Gun type foam adhesive ① When using a foam gun, clean it with polyurethane cleaner to ensure that the muzzle is unobstructed. ② Take the foam again, grip the middle of the can tightly with your hand, and shake it horizontally at least 15-30 times to ensure that the pre polymer inside the can is fully mixed. ③ Remove the protective cover of the valve on the threaded ring of the gun type foam adhesive, remove the cleaning agent from the foam gun, and install the foam agent tank onto the interface of the foam gun along the thread. ④ Grasp the handle of the foam gun tightly, ensuring that the material tank is placed above and the foam gun is below the material tank. Open the flow control valve at the back of the foam gun. ⑤ Aim the gun head at the bottom or inside of the area to be filled with the object, gently pull the trigger, and start construction. It can be adjusted to the appropriate flow rate through the flow regulating valve behind the foam gun. ⑥ After spraying a can, if you still need to fill it, you can immediately remove the empty can, reinstall the foaming agent according to the method in point three, and continue construction. ⑦ After the construction is completed, promptly remove the material tank and replace it with a specialized cleaning agent to clean the foam gun, in order to prevent residual materials from solidifying, blocking, and damaging the foam gun. 2. Pipe type foam adhesive ① The second step of using the gun style foam adhesive is the same as above. ② Take another disposable rubber hose and screw it clockwise. ③ Ensure that the material can is placed above and the foam gun is below the material can. Aim at the bottom or inside of the area to be filled with the object and gently pull the trigger to start construction. ④ Spray from bottom to top, with a spray volume of 80% of the required filling volume (2/3 for tubular filling volume). Precautions for foam adhesive Safety precautions ① Uncured foam is sticky to skin and clothes. Please do not touch skin and clothes when using ② There is a pressure of 5-6kg/cm2 (25 ° C) inside the foam tank, and the temperature during storage and transportation should not exceed 50 ° C to prevent tank explosion. The foam tank should be protected from direct sunlight ③ Children are strictly prohibited from touching, and empty cans after use, especially partially used but not yet used foam cans, should not be thrown around ④ Do not burn or puncture empty cans. Keep away from open flames and avoid contact with flammable and explosive materials ⑤ The construction site should have ventilation conditions. Construction personnel should wear work gloves, work clothes, and goggles during construction, and should not smoke ⑥ In case of eye contact with foam, please rinse with water before going to hospital; If it touches the skin, please rinse with water and soap Storage precautions ① It is strictly prohibited to invert and store in a dry, cool, and ventilated warehouse. Stay away from sources of fire and heat. The storage temperature should not exceed 30 ° C ② The normal operating temperature of the foam can is+5~+40 ° C, and the optimal operating temperature is+18~+25 ° C.

Nail-free adhesive is a strong adhesive that replaces traditional fastening methods like nails and screws. It's commonly used for attaching items like hooks, mirrors, shelves, skirting boards, and decorative panels. It's particularly suitable for smooth or difficult-to-perforate surfaces like tile, glass, metal, plastic, and wood. Proper application is key. Below are detailed instructions and precautions: I. Pre-Application Preparation Surface cleaning: Use a clean cloth or tissue to thoroughly remove any impurities such as dust, oil stains, water stains, and wax from the bonding area. For very smooth surfaces (such as tiles, glass, and metal), it is recommended to wipe and clean with alcohol or acetone to remove the invisible grease film to the naked eye, and then dry with a dry cloth. Make sure the pasting surface is completely dry. Item preparation: Clean the back of the items to be pasted (the pasting surface). Make sure the shape and material of the back of the item are suitable for pasting (flat or textured but in contact with the adhesive surface). Tool preparation: Nail-free glue (ensure it is within the shelf life); Rubber gun Utility knife A clean damp cloth or wet paper towel (for immediate cleaning); Tissues or old cloth; Level; Temporary fixing tools (such as masking tape, adhesive tape, heavy objects, support rods, etc.); Gloves. II. Apply the nail-free adhesive De-gluing: Unscrew the cap of the nail-free rubber tube, use a utility knife to cut the glue nozzle diagonally along the marked line (the size of the opening depends on the size of the adhered object and the required amount of glue), and then insert the rubber tube into the glue gun. Gluing method (very important) : Dot/Strip application: This is the most common and recommended method. On the back of the item to be pasted, apply continuous serpentine lines, dots or grid-like glue along the edge or center position. Do not cover the entire back! Amount of glue applied: Adjust according to the size, weight and material of the item. Heavier or larger items need to be coated with several more strips. The width and height of the adhesive tape/point are recommended to be around 3 to 8mm. If too little is applied, it won't stick firmly; if too much is applied, it may spill out, be difficult to clean and cure slowly. III. Pasting and Fixing Alignment: Quickly and accurately align the glued item with the position to be pasted. Once in contact, it's very difficult to adjust the position again! Use a level to ensure that the items are stuck horizontally or vertically. Pressure bonding: After alignment, press the item firmly onto the bonding surface for a few seconds to ensure that the adhesive is in full contact with both surfaces. Temporary fixation: Immediately use temporary fixation methods to firmly secure the item to prevent it from shifting or falling off. This is the key to ensuring the bonding effect! Common method: Masking tape/adhesive tape: Cross-stick it on the surface of the item and fix it on the wall/countertop. Support: Press heavy objects (such as books, boxes) onto the items, or support the items with wooden sticks, broom handles, etc. Suction cups/adsorption tools: For smooth surfaces such as glass. Fixed time: It is determined based on the brand of the nail-free adhesive, environmental temperature and humidity, as well as the load-bearing capacity. It generally requires at least a fixed 24 hours or more (extremely important!)" . For heavier items, damp environments or low-temperature conditions, it is recommended to fix for 48 to 72 hours or even longer. Do not remove the fasteners in advance! IV. Curing Waiting Initial curing (surface drying) : During the fixing period, the surface of the nail-free adhesive will gradually lose its stickiness (about 1-2 hours). At this point, it won't stick to the hand when touched, but the interior is still curing. Complete curing: It takes a relatively long time for the nail-free adhesive to reach its maximum strength. It usually takes 24 to 72 hours. The higher the ambient temperature and the greater the humidity (within a reasonable range), the faster the curing speed will be relatively. The curing process slows down in a low-temperature and dry environment. Load-bearing waiting: Do not hang heavy objects or apply tension on the adhesive until it is fully cured (at least 24 hours later)! Even if the surface is dry, the interior may not have reached its optimal strength yet. For items with heavy loads (such as shelves), it is recommended to wait for a longer time (such as 72 hours) before using them. V. Clean up the excess glue Immediate cleaning (best time) : After pressing and fixing, if any glue is found to be squeezed out, immediately wipe it clean with a clean damp cloth or wet paper towel. At this point, the glue has not yet cured and is the easiest to clean. Act quickly to avoid the glue spreading on the surface. Cleaning after curing: If the glue has already cured and hardened, cleaning will be extremely difficult. It can be carefully scraped off with a utility blade or a razor blade, especially suitable for hard and smooth surfaces such as glass and tiles. There are specialized nail-free glue removers available on the market. You can try using them (first test in a concealed area to see if they will damage the surface). Avoid using strong solvents, as they may seriously damage items or the paint surface of walls, the glaze surface of tiles, etc. VI. Important Notes Safety first: Avoid contact with skin and eyes. In case of accidental contact, rinse immediately with plenty of water. The glue on the skin will come off by itself after curing. Keep out of reach of children and pets. Keep the air circulating. Not edible! Applicable surfaces: Most suitable for: smooth, hard, non-porous or micro-porous surfaces, such as tiles, glass, metal, lacquered panels, PVC, solid wood, etc. Poor effect or inapplicable: Rough and porous surfaces (such as ordinary cement walls, gypsum boards, wallpaper, latex paint walls, loose wood, fabric, etc.). Heavy objects are prone to fall off when pasted on these surfaces. If it is to be used on surfaces such as latex paint walls, it is essential to ensure that the base layer of the wall is very solid and to increase the area of the glue application as much as possible, and to stick light and small items. Load-bearing capacity: The nail-free adhesive has a strong load-bearing capacity, but it has its limits. Be sure to understand the load-bearing capacity description of the purchased product and leave some margin. The larger and flatter the pasting area is, the stronger the load-bearing capacity will be. For particularly heavy items (such as large mirrors and heavy wall cabinets), it is strongly recommended to use mechanical fixation (such as expansion screws) in combination, with nail-free glue as an auxiliary seal and to prevent displacement. Environmental factors: Low temperatures (<5°C) or extremely dry environments can significantly slow down the curing speed and even affect the final strength. It cures faster in high-temperature and high-humidity environments. Avoid exposing it to a large amount of moisture immediately after pasting (such as taking a bath). Wait until it is completely cured before coming into contact with water. Removal: The cured nail-free adhesive is very difficult to remove completely. It usually needs to be scraped off with a blade, and the remaining part may be difficult to clean thoroughly. Removing items may damage the underlying surface (such as wall plaster). Before use, consider whether it needs to be removed in the future. Summarize the key steps: Thorough cleaning -> Dot/strip application of adhesive -> Quick and accurate alignment -> Press firmly -> immediate and firm fixation (24-72 hours) -> Wait patiently for complete curing (24-72 hours) -> Then bear weight. By strictly following these steps and providing sufficient curing time, the nail-free adhesive can exert a strong adhesive force, making your installation work both easy and secure

If the temperature is low, heating or extending the curing time should be used to promote curing. The use of structural adhesive Structural adhesive has high strength, peel resistance, impact resistance, and simple construction process. Used for bonding between the same or different materials such as metal, ceramic, plastic, rubber, wood, etc. It can partially replace traditional connection forms such as welding, riveting, and bolted connections. The stress distribution on the joint surface is uniform, and there is no thermal impact or deformation on the parts. Structural adhesive is widely used in engineering, mainly for strengthening, anchoring, bonding, repairing, etc. of components; Such as bonding steel, bonding carbon fiber, planting reinforcement, crack reinforcement, sealing, hole repair, road nail bonding, surface protection, concrete bonding, etc. What is weather resistant adhesive Weather resistant adhesive is a single component, neutral curing silicone sealant designed specifically for various curtain wall weather resistant seals. It has excellent weather resistance and has undergone artificial accelerated climate aging testing, with no significant changes in the physical and chemical properties of the sealant. When in use, use a glue gun to squeeze the glue from the sealant cylinder into the joint that needs to be sealed. The sealant absorbs moisture from the air at room temperature, solidifies into an elastic body, and forms an effective seal. The advantages of weather resistant adhesive Single component, easy to use, with good extrusiveness and thixotropy in the temperature range of 4 ℃ to+40 ℃. It can be directly applied by extruding with a glue gun; Neutral curing, non corrosive to building materials such as metals, coated glass, concrete, marble, granite, etc., widely used; The displacement capability reaches level 20, and this product can maintain its performance unchanged for normal expansion, contraction, and shear deformation of the curtain wall, providing effective sealing; Excellent weather aging resistance, aging resistance, UV resistance, ozone resistance, and water resistance; Excellent resistance to high and low temperatures, it will not become brittle, harden or crack even at low temperatures of -30 ℃ after curing, and will not soften or degrade at high temperatures of+90 ℃, maintaining good elasticity at all times; Having excellent adhesion, it forms a strong bond with most building materials after curing without the need for a primer; It has good compatibility with other neutral silicone adhesives. The use of weather resistant adhesive Used for weather resistant sealing of various glass curtain walls; Used for weather resistant sealing of metal (aluminum plate) and enamel curtain walls; Used for joint sealing of concrete, metal, etc; Sealing of roof building joints. The difference between structural adhesive and weather resistant adhesive Different uses weather proofing sealant Suitable for weather resistant sealing of various curtain walls, especially recommended for glass curtain walls, aluminum-plastic panel curtain walls, and stone dry hanging weather resistant sealing. Sealing of joints between metal, glass, aluminum, ceramic tiles, organic glass, and coated glass. Sealing of joints on surfaces of concrete, cement, masonry, rock, marble, steel, wood, anodized aluminum, and painted aluminum. In most cases, primer is not necessary. structural adhesive Mainly used for structural or non structural bonding assembly between metal and glass in glass curtain walls. It can directly connect glass with the surface of metal components to form a single assembly component, meeting the design requirements of curtain walls with fully hidden or semi hidden frames. Structural bonding and sealing of insulating glass. Function location Weather resistant sealant is mainly used for sealing and filling joints between materials, as well as waterproof sealing of joints; Structural adhesive is mainly used for bonding structural and non structural assemblies of various curtain walls, and their functions are different. Adhesive performance Weather resistant sealant, also known as universal adhesive, mainly has the ability to resist extreme weather conditions such as ultraviolet radiation, acid rain, and snow. The displacement ability of weather resistant adhesive (which can be explained as elasticity) is higher than that of structural adhesive. Silicone structural adhesive not only has the characteristics of weather resistant sealant, but also has stronger bonding performance than weather resistant sealant, mainly manifested in strong tear resistance, fracture elongation, and tensile strength. Tensile strength is mainly used in pre stressed areas. The modulus, hardness, strength, and price of structural adhesive are higher than those of weather resistant adhesives of the same grade. Summary: The weather resistance of structural adhesive is as good as or even better than that of weather resistant adhesive, because the weather resistance of structural adhesive is related to safety. If it ages quickly, the consequences of glass falling off are very serious. Therefore, most structural adhesives nowadays are silicone (silicone adhesive), which will not age in natural environments. Weathering glue does not involve safety, and the main result of failure is usually water and air leakage. Therefore, there are many types of materials for weathering glue, including polyurethane, polysulfide, acrylic, etc., but silicone is still the best for weather resistance.

Applying sealant to the home during decoration is an essential task, as many areas need to be sealed during the decoration process. By applying sealant, the gaps can be filled completely to prevent water leakage, mold growth, and dirt accumulation. Applying sealant is a small detail in the decoration process. Many first-time decoration enthusiasts do not know where to apply sealant and what kind of sealant to apply. Today, we will explain it to everyone in one go.   There are two main types of sealants used for home decoration: beauty sealant and glass sealant. Their characteristics are different, and the places they use are also different.   Beauty glue is usually a type of sealant with good flexibility and weather resistance. After curing, it has a certain degree of elasticity and can deform with the expansion and contraction of the material, making it less prone to cracking. The color of beauty glue is diverse and uniform, and it can usually match various decoration styles and material colors. One of its design purposes is to beautify the gaps, making them look cleaner and more delicate. The main components of glass adhesive are sodium silicate (Na2O · mSiO2), acetic acid, and organic silicone. It has strong adhesion, but its elasticity and stain resistance are generally not as good as beauty adhesive. Glass glue has relatively few colors, with common basic colors such as transparent, white, and black. In terms of decorative effect, it mainly serves as a simple filling and sealing function.   Where do I need to apply sealant? What kind of sealant should be applied?   Kitchen countertop (coated with anti mold glass glue) Regardless of whether the kitchen countertop has a water stopper, a circle of sealant needs to be applied. If sealant is not applied, oil fumes, water stains, and dust from cooking in the kitchen will accumulate in the gaps. Over time, the more they accumulate, the more mold and bacteria will grow, and the gaps will become hygiene blind spots that are difficult to clean. And ordinary sealant cannot be used in the kitchen, as it is prone to mold, yellowing, and blackening. Be sure to use formaldehyde free anti mold glass glue, which is environmentally friendly, waterproof, and anti mold, making it easier to use. Anti mold grade: Buy strong anti mold glue with a high anti mold ratio, the higher the ratio, the longer the anti mold time. When applying glue, it is important to note that the gaps between kitchen countertops should not be sewn with beautiful seams, as they lack toughness after curing and are prone to cracking and falling off. Toilet shower outlet (coated with anti mold glass glue)There is a gap between the shower outlet on the bathroom wall and the ceramic tiles. If no sealant is applied, water will flow into the sand and dust layer through the gap in the later stage. The sand and dust layer will be in a damp state for a long time, which will lead to a decrease in the bonding strength of the sand and dust, and there is a risk of hollowing and falling off the ceramic tiles. So after the bricklayer is finished, it is necessary to apply anti mold glass glue. In case of water leakage, it can also prevent water from entering the sand and dust layer and causing unnecessary losses. Apply glue around the window frameBecause glass glue has shrinkage, when combined with latex paint, it will crack the latex paint tape after shrinkage. After the installation of the window, apply glass glue to the junction between the window frame and the tiles to make it more secure, prevent air and rain leakage, and also serve as a shading effect. The glass glue for window closure is usually applied by the window installer, and other glue applicators are not as good as them. Make a circle around the door frame (beauty glue)After installing the door at home, there are gaps between the door frame and the latex paint on the wall. Some people choose to use latex paint to fill the gaps, but over time, the door frame will vibrate and the latex paint is prone to cracking. So it is more suitable to use beauty glue at the junction of the door frame and latex paint wall. Kicking line and bottom (applying beauty glue)All the skirting boards at home should be coated with beauty glue to prevent water from entering the wall through the gaps of the skirting boards, causing mold and peeling on the wall. When playing, be careful to apply white or a color similar to the skirting board on top, and remember to apply transparent beauty glue to the area where the tiles meet below for better visibility and less abrupt appearance. Bathroom countertop (coated with anti mold glass glue)The bathroom cabinet uses water for a long time, and if it is not glued around, it is prone to water leakage. Being in a humid environment for a long time can easily lead to the growth of bacteria. So a circle of glass glue should also be applied between the bathroom cabinet and the wall tiles, and it should be anti mold and waterproof. Poor quality glass glue is prone to yellowing and mold growth, and it won't last long. Around the bottom of the toilet (apply glass glue)Apply a circle of glass glue between the toilet and the floor, just like applying glue to bathroom cabinets, choose anti mold glass glue. Applying ordinary glass glue can easily cause yellowing, blackening, and mold growth. Glue is applied to make the toilet and floor more secure, and to prevent water from entering the bottom of the toilet and growing bacteria. You must apply the correct sealant to these 7 areas of your home in order to make it better to live in. Have you learned? Company website: www.gfkjgs.com

Summer has arrived, with temperatures rising. As the most complex and variable season of the year, extreme weather such as sustained high temperatures, heavy rainfall, hail, and even typhoons occur frequently. At this point, improper use or maintenance of single component silicone sealant can easily lead to various quality problems after construction.   To ensure its stable and reliable performance, this article will focus on the key precautions for its use during summer and rainy seasons. Part 01 Curing Principle The curing reaction of single component room temperature cured silicone rubber is to react with water molecules in the air and solidify into an elastic body. The curing process starts from the surface and gradually moves towards the interior. The curing speed depends on the curing system, temperature, humidity, and thickness of the silicone rubber layer. Increasing the temperature and humidity of the environment within a certain range can accelerate the curing process. Using it in a conventional environment with a relative humidity of 55% RH at 25 ℃ is a reasonable and satisfactory environment that can achieve the appropriate use state of silicone gel.   Part. 02 Common Problems Extended drying time Extended deep curing time Colloidal surface becomes sticky Weakening of bonding strength per unit time ........... Due to the high moisture content in the air during the rainy season, the surface of the adhesive undergoes excessive hydrolysis, resulting in a prolonged drying time and a "sticky" surface, which delays the adhesive strength for a certain period of time. However, as the curing time increases, the bonding strength will correspondingly delay until the adhesive performance is fully cured and restored.   Precautions Before use, remove moisture, oil stains, dirt, etc. from the surface of the adhesive material, wipe it clean, and then use it to avoid adverse reactions such as insufficient adhesive strength and curing failure. The bonding strength may vary greatly depending on the bonding interface, and corresponding interface bonding strength tests should be conducted before use. RTV silicone rubber starts to cure from the surface to the inside when it comes into contact with water molecules in the air, and the curing depth is limited. Generally, the curing depth is less than 6mm after sufficient curing. In addition, the surface drying time and depth curing time may vary with the temperature and humidity of the adhesive environment.   Part 03 Summary&Suggestions The curing of some RTV is related to temperature and humidity. Within a certain range of temperature/humidity, the curing depth of RTV is fast. If unilaterally cured by moisture (relative humidity above 90% RH), the colloidal surface will appear sticky. It is recommended to extend the storage time of the product that has been glued (the specific extension time needs to be combined with the product and application environment). Apply glue under environmental conditions of temperature (27 ℃± 2 ℃) and humidity (55% -70% RH). To ensure the best use effect, please pay attention to the changes in the glue state during summer, adjust the construction plan reasonably, and give the glue sufficient curing time to avoid affecting the quality of the project due to insufficient curing.

High temperature and humidity are the norm in summer. If silicone sealant is not used properly, it is very likely to cause various problems, such as bubbling and bulging. The following silicone sealant construction guide will help you easily cope with the summer challenges. First, temperature and humidity are crucial 1. Temperature control Avoid high-temperature periods: Try not to carry out construction when the surface temperature of the base material exceeds 40℃ (such as metal and glass surfaces exposed to intense sunlight). Preferred construction periods: Early morning, evening or cloudy days are the best times for construction. Avoid direct sunlight and excessive temperature differences. 2. Humidity management Pay attention to humidity changes: The relative humidity of the construction environment is best maintained between 40% and 80%. Low humidity will significantly slow down the curing speed and increase the risk of bulging. Outdoor construction is strictly prohibited on rainy days: Stop outdoor gluing operations on rainy days! Before applying the glue after the rain, make sure to check whether the inside of the joint is damp and there is any residual moisture. Residual water vapor can affect the adhesion between the sealant and the substrate, and even cause bubbling problems. Second, choosing the right materials is the foundation 1. Observe the displacement capacity Select products with appropriate displacement capabilities based on the application scenarios. For projects with narrow joints, it is essential to select sealants with a high displacement capacity grade to accommodate the greater thermal expansion and contraction deformation in summer. 2. Check the weather resistance performance Select silicone sealant with good weather resistance and strong UV resistance to ensure a long service life. 3. Check the environmental protection performance Choose products that comply with relevant environmental protection standards (such as GB 33372-2020, GB 18583-2008, etc.). Third, meticulous operation ensures quality 1.Pre-construction test For single-component silicone sealant, it is recommended to conduct a simple surface drying time test (squeeze a small amount of sealant to observe the time it takes for the surface to form a skin) before applying the sealant to understand its performance under the current temperature and humidity conditions and guide subsequent adjustments and the speed of applying the sealant. 2. Key points during construction Lay a solid foundation: The base material should be clean, free of oil stains and dust, and dry is a prerequisite (especially after resuming work after rain). Standard operation: The glue injection should be full and continuous, and the trimming should be timely and in place. In summer, metal curtain walls are prone to bulging problems. How can this be avoided? The two-step gluing method is adopted: that is, first apply a concave glue joint, with the thickness of the glue applied controlled at half the depth of the joint. After it has cured for 2 to 3 days and becomes elastic, apply the second layer of glue on its surface. It should be noted that when applying the second coat of glue, the surface of the first coat of glue should be kept clean and free of dust and other stains; otherwise, the two coats of glue cannot form an effective bond. Fourth, store properly to prevent deterioration The warehouse should be cool: Store in a dry and cool warehouse, and avoid direct sunlight on the colloid. Moisture-proof and ventilation: During the rainy season, enhance ventilation. Moisture-proof boards can be laid on the ground or rubber piles can be raised to prevent moisture. Sealed storage: Unopened glue: Keep dry and vacuum-sealed. Opened adhesive (such as half tube) : The adhesive at the tube mouth will naturally harden to form a seal. The next time you use it, just pick off or squeeze out the hardened part of the pipe mouth and you can continue to use it. Be sure to use it up in time. Company website: www.gfkjgs.com

Its excellent weather resistance is a core competitiveness. Whether facing the scorching sun, heavy rain, or severe cold and frost, the product can maintain stable performance. After years of use, it can still maintain good elasticity and sealing, providing reliable protection for the project for decades. ​ "Advanced fast-drying acidic glass silicone sealant" has a wide range of application scenarios: in the field of glass engineering, it can perfectly achieve the bonding and sealing of various indoor and outdoor glass; when used in decoration projects, it can accurately complete the caulking operation, adding a sense of refinement to the decorative details of walls and floors; for home scenes, the bonding and sealing of cabinets and tiles are also handy; in the installation of doors and windows, it is especially suitable for aluminum alloy glass doors and windows, which can ensure a firm connection and efficient sealing.

The curing speed of building silicone sealant has a significant impact on construction speed and may also affect the performance of the sealant. This issue analyzes the curing process of single component silicone sealant and the factors that affect the curing speed. Curing mechanism of single component silicone sealant Single component building silicone sealant is mainly a condensation type silicone rubber, and its curing mechanism is that it can undergo condensation reaction upon contact with atmospheric moisture, cross-linking into an elastic body. The curing process involves contact with moisture in the air, gradually solidifying from the surface to the interior. Factors affecting curing speed The curing speed of single component building silicone sealant is related to its own formula, as well as the humidity and temperature of the environment, and the diffusion speed of moisture in the adhesive layer. 01 Environmental temperature Because the curing process of sealant is a chemical reaction process, the temperature of the environment has a significant impact on its chemical reaction rate (curing rate). The higher the ambient temperature, the faster the curing speed will be. In general, when the temperature is below 15 ℃, the curing speed of the sealant will significantly decrease. For single component sealant, the complete curing time under low temperature conditions will be much longer. You should also feel the difference in curing speed between building sealants in summer and winter. 02 Environmental humidity During the curing process of sealant, water molecules play a crucial role in its chemical reaction. For single component sealant, its curing process requires absorbing moisture from the air, so within an appropriate humidity range, the higher the humidity in the atmosphere, the faster the curing speed will be; The lower the humidity, the slower the curing speed. Especially in the dry seasons of autumn and winter, the decrease in environmental humidity will prolong the complete curing time of single component sealant! 03 Surface area of sealant in contact with air Single component sealant is greatly affected by the contact area with air, especially when applied to sealant joints on non porous substrates such as glass, metal, etc. Only one side of the sealant can come into contact with air, and the other three sides in contact (such as glass, aluminum, and gasket materials) are basically impermeable. At this point, the larger the effective contact area between the sealant and air, the more moisture it can obtain, and the faster the curing speed will be. 04 Ventilation environment The sealant should be placed under ventilated conditions. In a completely enclosed environment, the small molecular substances released during the curing reaction of the sealant will gradually accumulate, and their concentration will rise to a certain extent, which will prevent further curing reaction and ultimately lead to insufficient curing of the sealant, failing to achieve the optimal performance of the sealant. Meanwhile, if the water consumed by the reaction is not replenished, its solidification will slow down. Therefore, the construction environment of sealant must ensure ventilation, and it cannot be in a completely sealed environment during the curing process. 05 sealant formula itself In addition to external factors, the curing speed of silicone sealant is also closely related to the formula. GuFeng Technology is committed to providing safe and healthy alcohol based environmentally friendly sealants for our customers, and continuously innovating and researching to improve the curing speed of alcohol based sealant products, meeting users' demand for rapid curing of alcohol based environmentally friendly sealants.
