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® PC5410 is used as crosslinkers in silicone rubber systems.
SiSiB® PC5410 is used as drying agents in sealing compositions.
SiSiB® PC5410 is used as an important starting material for sol-gel processes.
