This chemical is primarily used as a UV absorber in various coatings and polymers to enhance their resistance to ultraviolet light. It is particularly effective in protecting materials from degradation caused by prolonged exposure to sunlight, such as in automotive paints, plastics, and adhesives. The triethoxysilyl group in its structure allows it to bond chemically with siliceous surfaces, making it suitable for use in glass coatings and other silica-based materials. Additionally, it is employed in the formulation of sunscreens and personal care products to provide protection against harmful UV rays. Its ability to stabilize and extend the lifespan of materials makes it a valuable additive in industries focused on durability and performance.
