Silicone-Based Coatings for PET Films

Silicone materials are generally composed of silicon-oxygen chains as the basic structural unit, and the side chains can be connected to various other organic groups through silicon atoms. Therefore, the structure contains both "organic groups" and "inorganic structures". The special composition and molecular structure make it combine the characteristics of organic matter and the function of inorganic matter.
Silicone coatings are often used as materials for transparent wear-resistant coatings due to their good light transmission. This kind of coating has sufficient flexibility and good bonding performance with the base material; there is no double bond in the main chain, so it is not easy to be decomposed by ultraviolet light and ozone, even if it is exposed outdoors or in an environment with high ozone concentration for a long time. There will be no cracking and viscous creep, and there will be basically no change in physical and electrical properties;
Resin-type silicone coating materials will not yellow even under strong ultraviolet radiation, and their color can remain unchanged for many years, so many scientific and technological workers have carried out research in this area. According to Coating Online, if a variety of nanoparticles are introduced into the coating as reinforcements, the wear resistance and compactness of the coating can be further improved.
