Product Code：SP8031
Product Name：Methyltrimethoxysilane
Product Introduction：
Methyltrimethoxysilane is an organosilicon compound with one methyl and three hydrolyzable methoxy groups. It acts as a hydrophobic surface modifier, crosslinker for silicone resins, and adhesion promoter. Its methoxy groups undergo rapid hydrolysis and condensation, forming stable siloxane networks. It is widely used in sealants, coatings, and as a water repellent for inorganic fillers.
