Product Information
Tetramethyldivinyldisiloxane is a clear, low-viscosity vinyl-functional disiloxane. It provides reactive vinyl groups for hydrosilylation and polymer modification, making it a useful building block in the production of vinyl silicone oils, vinyl silicone resins, silicone gels and addition-cure silicone rubber systems.
Typical Applications
- Intermediate for vinyl silicone oil, vinyl silicone resin, liquid silicone rubber and silicone gel.
- Functional modifier or end-blocking agent for specialty siloxane polymers.
- Component or ligand used in platinum-catalyzed hydrosilylation catalyst systems.
- Used in specialty organosilicon synthesis and advanced material research.
