Introduction:

Silicon esters are silicon compounds that contain an oxygen bridge from silicon to an organic group, for example, Si-OR. YokoSil™ E10, the methyl ester of orthosilicic acid, is a colorless, low-viscosity liquid. It is industrially the most important of the tetraalkyl silicates.

Application:

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.

YokoSil™ E10 is used as crosslinkers in silicone rubber systems. YokoSil™ E10 is used as drying agents in sealing compositions. YokoSil™ E10 is used as an important starting material for sol-gel processes.
