| SiSiB® PC5440
Tetrabutoxysilane (TPOS) .
Synonym: Silicon Tetra-N-Butoxide;
Tetra Butyl Orthosilicate
|
The ethyl group of ethyl silicate is replaced by N-butyl, so the speed of hydrolysis is even slower than N-propyl silicate, and in addition to a cross-linking agent for silicon rubber, and a modifying agent for organic and inorganic resins, it can also be used as a heating medium or cooling medium by making it a condensate. There are also hopes for applications to electron donors in Ziegler-Natta catalysts.
