Dimethyldimethoxysilane Usage And Synthesis

Description

Dimethyldimethoxysilane 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.

Dimethyldimethoxysilane is mainly used in these aspects:

  • In the synthesis of chemical intermediates.
  • As an additive for the production of silicone resins.
  • In the hydrophobization of surfaces, like glass, pigments etc.
