Product Description
Product Details
Introduction
Modified methyltriacetoxysilane is used in the preparation of deacidified RTV silicone rubber. Because methyltriacetoxysilane with a higher monomer content is very easy to crystallise at low temperatures, its crystallisation at low temperatures can be avoided by replacing an acyloxy functional group on its molecule with a methoxy functional group.
