Products in Monomers & Intermediates: Silicates

Dynasylan® A is also known as TEOS (tetraethoxysilane), is the ethyl ester of orthosilicic acid. This colorless, low-viscosity liquid boasts a SiO content of 28.5%. Utilization involves acid- or alkali-catalyzed hydrolysis, leveraging all four ethoxy groups for reaction and earning it tetrafunctional status. Hydrolysis initiates silanol group formation, which further condenses to establish robust siloxane bonds (-Si-O-Si-). Notably, condensation begins before hydrolysis concludes, with ongoing condensation during storage resulting in gel formation. Gelation rate hinges on water concentration.

AL T-99 TEOS is high purity tetraethyl orthosilicate (TEOS) monomer.

BlueSky Chemical D-130 (SI28) Crosslinking Agent is a good penetration, due to small molecular size. It is an inorganic binder and UV stable. Used for sol-gel processes in combination with other alkylsilanes such as D-150 Silane.
