Methylvinyldimethoxysilane: Guide
Methylvinyldimethoxysilane is a key organosilicon monomer and silane coupling agent. With its reactive vinyl group, it enhances adhesion by bonding with organic materials and introducing new functional groups.
Applications:
- Surface modification of glass fibers and inorganic fillers
- Formulation of sealants and adhesives, including LED encapsulation sealants
- Synthesis of cyclic methyl vinyl siloxane, a crucial raw material for methyl vinyl silicone rubber (VMQ)
