SiSiB® PC5430

Tetrapropoxysilane

SiSiB® PC5430, [also called n-Propyl Silicate] is used as a cross-linking agent for silicon rubber, and as a modifying agent for organic and inorganic resins. The ethyl group of ethyl silicate is replaced by the N-propyl group, so the speed of hydrolysis is slower than ethyl silicate. It is equal to Evonik's Dynasil P.
