Tetraethoxysilane

Chemical name: Tetraethyl orthosilicate

English name: Tetraethoxysilane

CAS NO: 78-10-4

Molecular formula: C8H20O4SI

Density: (25 ℃): 0.94g/ml

Boiling point: 168 ℃/760mmHg

Folding rate: (20 ° C): 1.382

Flash point: 46 ℃

Physical standards: colorless flammable liquid, irritating odor

Use:

It is mainly used as optical glass, chemical resistance coatings and heat -resistant coatings and adhesives. CVD and SOL-GEL Legal prepare SIO2 and multiple components containing SiO2 components. It is used to synthesize the silicon intermediate, as well as an cross -linked agent for refractory adhesives and precision casting. For coatings and heat -resistant coatings for chemical resistance, its hydrolyzed products can make fluorescent powder.

It is used for natural stones or other building materials, which can form a silicone -soluble -like inorganic substance (SIO2) to enhance the strength of the substrate. In glass and plastic lens materials, D-130 (SI28) can provide it with super hard scratch coating.
