Short Description:

Product: Dimethyldimethoxysilane(DMDMOS)

CAS 1112-39-6

Purity: 99%

Packing: 1kg/bottle or 25kg/drum

Dimethyldimethoxysilane(DMDMOS) is a monomeric alkylalkoxysilane. It hydrolyzes in contact with water, releasing methanol, to form highly reactive silanols, which further condense to form oligomeric and polymeric siloxanes.
