Ultraviolet stabilizers, especially ultraviolet absorbers (UV absorber, UVA), and hindered amine light stabilizers (HALS), have proven to be effective in protecting coatings. When coatings are exposed to sunlight over time, issues such as loss of gloss, color fading, and chalking may occur as part of coating degradation. This natural degradation is often considered an inherent characteristic of polymers, but it can be improved by incorporating specific additives into the coating. These additives find applications in wood, metal products, vehicles, roofs, aircraft, and more.
Specifically, the choice of polymer, the use of ultraviolet stabilizers, and the proper application methods all significantly impact the lifespan of coatings. This is especially crucial for coatings with outstanding durability, such as those used in skyscrapers, where the lifespan is notably extended. This emphasizes the importance of expertise in material selection, additive use, and processing techniques in increasing the lifespan of coatings.
