Applications

The tetraalkyl orthosilicates ( also called orthosilicic acid esters) most commonly used as starting materials for sol-gel.

Polysilicic acidesters are condensation products obtained by incomplete hydrolysis or orthosilicic acid esters. They are also be used as starting materials for the sol-gel process.

SiSiB® PC5460 can be used to modify suface of silica to obtain hydrophobic property. SiSiB® PC5460 can be used as crosslinkers for room temperature vulcanizing silicone sealant.
