Used as a surface modifier in coatings and sealants to improve water repellency and reduce surface energy. Enhances durability and weather resistance in architectural and industrial finishes. Acts as a coupling agent in silicone-based formulations, improving adhesion between organic and inorganic materials. Commonly applied in release coatings, where low surface tension is critical for mold release and anti-stick performance. Also utilized in specialty formulations for electronics and optics to provide moisture protection and improve compatibility between dissimilar phases.
