Tetramethoxysilane : Guide
Tetramethoxysilane is a commonly used organosilicon compound that can be obtained through hydrolysis reaction to obtain dimethoxysilanols. Si(OCH3)4 is usually used as the starting material for the synthesis of silicone (siloxane). Silicone is a polymer with silicon-oxygen bonds (Si-O) that is widely used in coatings, sealants, adhesives and materials science. As one of the precursors for silicone synthesis, TMOS can participate in the polymerization reaction of silicone and be used to prepare silicone materials with specific properties.
It should be noted that TMOS is a highly reactive silicon-based organic compound that hydrolyzes quickly, so it needs to be handled carefully when used to avoid contact with moisture and moisture to ensure that the synthesized or prepared materials have the required properties.
