Tetrapropoxysilane (TPOS) .
Synonym: Tetrapropyl Orthosilicate;
Tetrapropyl Silicate.
Countertype of Evonik DYNASIL P
Chemical Structure
Introduction
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.
