Product description
Empirical formula: C8H20O4Si
Molecular weight: 208.33
CAS No.: 78-10-4
Chemical name: Tetraethylsilane, Tetraethyl orthosilicate
Properties
Good penetration, due to small molecular size.
Inorganic binder, UV stable.
Used for sol-gel processes in combination with other alkylsilanes such as D-150 Silane.
Reactivity
Tetraethyl orthosilicate (TEOS) will react with moisture to form a silica-gel like binder and ethanol byproduct which evaporates.

Application and performance
130(SI28)Silane that can be applied neat, diluted or as part of a formulated product. Applied to natural stones or other construction materials, it forms a silica-gel like binder (SiO2) that increases the substrate strength.
Polymerization of silicone resins for use in paints and other surface modification applications intermediate for sol-gel process.
For the manufacture of sealant materials RTV-2, D-130(SI28)can be used as a cross-linking agent.
On glass and plastic lens materials, D-130(SI28)silane provides a scratch-resistant, hard-coat to the finish.
