SiSiB® PC1730 is an excellent adhesion promoter that can be used in many resin systems. The silane exhibits very good thermal stability and is useful in high temperature applications that are also exposed to moisture.

The secondary amine is useful in systems where only one reaction between resin and silane is desired (such as NCO terminal polymers).

SiSiB® PC1730 is also reactive toward epoxy, phenolic, urethane, imide, and melamine resin systems.
