description Product Description
Used as a key intermediate in the synthesis of silane coupling agents, which are widely applied in adhesives, sealants, and composite materials to improve bonding between organic and inorganic components. It serves as a precursor in the production of specialty silicones for coatings and elastomers, offering enhanced thermal stability and water repellency. Also utilized in surface modification of fillers and pigments in polymer formulations to improve dispersion and compatibility. Its reactivity makes it valuable in controlled hydrosilylation reactions for manufacturing functional fluids and release agents.
