Product Description
Ethyl Silicate
OVERVIEW
English Name: Ethyl Silicate English Alias: Tetraethyl orthosilicate
CAS: 78-10-4 Molecular formula: C8H20O4Si
EINECS: 201-083-8 Molecular Weight: 208.32700
PROPERTIES
Appearance: Clear colorless liquid with a faint odor.
Density: 0.934 Melting Point: -77 °C Boiling Point: 168°C(lit.)
Flash Point: 45°C Refractive Index: n20/D 1.382(lit.) Vapor Pressure: <1 mm Hg ( 20 °C)
Water Solubility: Hydrolysis
Stability: Stable. Flammable. Incompatible with strong oxidizing agents, water, alkalies, mineral acids.
Storage: Flammables area.
SAFETY INFO
UN: UN 1292 3/PG 3 Risk Statements: R10; R20; R36/3 Safety Statements:: S16-S36/37/39
WGK Germany: 1 RTECS: VV9450000
Hazard Codes: GHS02, GHS07,
USAGE
It is used in precision casting as sand mould binder, and the metal surface treated with ethyl silicate is anticorrosive and waterproof. Ethyl silicate can be used to siliconize metal surface, treat optical glass to improve the transmittance, and produce ultra-fine silica powder after complete hydrolysis can be used to make phosphors. Ethyl silicate is the raw material of organic silicone oil. It can also be used to manufacture heat-resistant and chemical-resistant coatings. 90% Ethyl Silicate Used as Material for Anticorrosive Coatings (Zinc-rich Paint).
