- General Information: It is a bifunctional polysulfide silane with two sulfur atoms in the center of the structure that finds use as adhesion promoter for precious metals, and coupling agent & vulcanizing agent for rubbers. Comparing to S4, it contains lower active disulfide functional group and so can offer better scorch safety.
- Suitable Usage: Mainly but widely used in rubber industry
