Methyltrimethoxysilane CAS NO.1185-55-3

This product is a colorless, low-viscosity liquid, regarded as trifunctional since all three alkoxy groups are able to participate in this reaction. Additionally it contains a methyl group that adds organic character to the products. Hydrolysis leads to silanol groups which, in a subsequent condensation reaction, form very stable siloxane bonds (-Si-O-Si-).
