Product Details
Introduction
Diphenyldimethoxysilane is a single-component organosilane obtained by alcoholysis of diphenyldichlorosilane by methanol. It is mainly used in propylene polymerization to improve isotacticity. It can be used as a crosslinking agent for silicone resins and as a raw material for phenyl silicone oil and silicone rubber.
