- Chemical Family
- Siloxanes
Evonik Polymer VS 165000 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.

- Application
Polymer VS cures by a platinum-catalyzed addition reaction with silicone crosslinkers containing SiH groups. Due to the low content of volatile constituents and the crosslinking mechanism, the curing shrinkage remains low and no volatile or corrosive substances are formed while curing. Polymer VS can be used for a wide range of applications by selecting the suitable crosslinkers (Crosslinker 100 series, Crosslinker 200 series), catalysts (Catalyst 500 series), additives and fillers.
