Phenyltriethoxysilane: Guide
Phenyltriethoxysilane is primarily used in the production of high molecular organosilicon compounds, as a crosslinking agent for silicone resin, and as a key ingredient in phenyl silicone oil and silicone rubber.
Applications:
- Acts as a hydrophobic additive in silane coupling agents.
- Used as raw material for phenyl silicone oil and silicone rubber.
- Functions as a crosslinking agent for organic resins, particularly in coatings, sealants, and adhesives.
