Eversorb UV stabilizers protect construction sealants from UV light, prevent yellowing, cracking, adhesion loss, and extend the durability.

Sealants in Our Daily Lives

Sealant owns various functions such as joint, waterproof, moisture-proof and fireproof; therefore it is widely applied in different parts of a building, such as doors, windows, exterior walls, bathrooms, kitchens, and stairs. Compared to traditional resin, the hybrid polymer provides several advantages, including non-toxic, odorless, fast curing speed, and excellent adhesion, which makes it a growing trend to use hybrid polymer as the base resin for construction sealants.


Construction Sealants in Our Daily Lives


Cracking, Yellowing, Adhesion Loss Lead to Dangerous Buildings

However, after exposure to UV light and extreme temperature and humidity conditions, degradation occurs and leads to various physical property damages, such as yellowing, discoloration, chalking, and cracking. For the worst, it would result in delamination or loss of adhesion. These problems will then cause unwanted leakages of water or air; furthermore, the window glass or other parts might fall due to loss of adhesion!
