PROSILANE™ SC-5931
Product Description
n-Propyltrimethoxysilane is an organosilicon compound with one propyl group (C₃H₇) attached to a silicon atom, which is further bonded to three methoxy groups. It is a clear, colorless to pale yellow liquid that is primarily used as a coupling agent, surface modifier, and adhesive promoter. It is known for enhancing the bonding of organic materials to inorganic surfaces like glass, metal, and ceramics and improving the weather resistance and durability of coatings and adhesives.
