Evonik Polymer VS 200
- Chemical Name
- Polydimethylsiloxane
- Chemical Family
- Siloxanes
Evonik Polymer VS 200 consists of vinyl-terminated polydimethylsiloxanes available in different viscosity levels and molecular weights, with an impressively low content of volatile constituents. These polymers serve as fundamental components in silicone formulations that cure through a platinum-catalyzed addition reaction with silicone crosslinkers containing SiH groups. The minimal presence of volatile constituents and the crosslinking mechanism ensure that curing shrinkage remains low, and no volatile or corrosive substances are generated during the curing process.
