Used primarily as a surface modifier in silicone-based formulations, this compound enhances water repellency and surface compatibility in coatings, adhesives, and sealants. Its reactive chloromethyl group allows for covalent bonding to various substrates, improving durability and adhesion. Commonly applied in release coatings, it modifies surface energy to prevent sticking. Also utilized in the synthesis of functional silicones for use in personal care products, where it contributes to spreadability and film formation. Its low surface tension improves wetting and leveling in industrial applications.
