description Product Description
Used as a surface treatment agent in silicone chemistry, this compound functions effectively in modifying the surface properties of fillers and pigments. It enhances compatibility between hydrophobic silicone matrices and inorganic materials, improving dispersion and reducing viscosity in silicone formulations. Commonly applied in sealants, adhesives, and elastomers to promote better adhesion and stability. Also serves as an intermediate in the synthesis of specialty silanes for coatings and water-repellent treatments. Its acetoxy group allows for controlled reactivity under mild conditions, making it suitable for moisture-curable systems.
