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® PC5420 may be used as an inorganic binder for refactory fillers and pigments, like precision investment castings.

SiSiB® PC5420 may be used as a second backup casting coating. It cures faster than colloidal silica system.

SiSiB® PC5420 may be hydrolyzed to form silicon dioxide (silica).

SiSiB® PC5420 may be used as a starting material for sol-gel process.

SiSiB® PC5420 may be used as a crosslinking agent for silicone sealant.

SiSiB® PC5420 may be used as a drying agent in sealing compositions.

SiSiB® PC5420 may be used as a chemical intermediate.
