3. How to choose high-quality door and window silicone sealants?
(1) Weather resistance and waterproofness: It can adapt to changes in high and low temperatures, maintain good performance under severe cold and high temperature conditions, and has good waterproof performance to avoid aging or falling off caused by rainwater penetration.
(2) Adhesion: For most building materials, such as glass, coated glass, painted metal, etc., it has good adhesion and sealing ability to avoid wind and rain leakage.
(3) UV resistance and anti-aging: After curing, it forms a strong and elastic silicone rubber that is not affected by rain or snow.
(4) Environmental protection: safe and non-toxic, no odor, harmless to the human body and the environment
(5) High mobility and permanent flexibility: The sealant of doors and windows needs to have a certain elasticity, be able to cope with the expansion and contraction between materials caused by temperature changes, humidity changes and other factors, and not easy to crack or deform.
3. How to use silicone door and window sealant?
(1) Make sure the surface of the door and window is dry and clean
(2) Use a glue gun to evenly apply the silicone door and window sealant to the joints
