Description
Technical Parameters
Introduction: Ultra low volatile vinyl polysiloxane combines low volatility characteristics with high reactivity, and is easy to crosslink and cure.
Application: Mainly used as a diluent for liquid silicone rubber (LSR), base polymer, as well as high-end potting adhesive and high-temperature resistant coating.
