Applications
1. Tetraethyl orthosilicate is Used as insulating materials in electronic industry, also used for optical glass processing and used as coagulants.
2. For precision casting, as a sand binder. Metal surface treated by ethyl silicate vapor can be anticorrosion and waterproof. Ethyl silicate can be used to bleed on the metal surface of the silicon, processing optical glass can improve its light transmittance. Fine silica powder produced by complete hydrolysis can be used to manufacture the phosphor. Ethyl silicate is raw material for silicone oil. Ethyl silicate can also be used to manufacture heat-resistant, chemical-resistant coatings. In Japan, 90% of ethyl silicate is used as an anti-corrosion coating (zinc-rich paint) base material.
3. Tetraethyl orthosilicate is Mainly used in chemical-resistant coatings and heat-resistant coatings, used as silicone solvent and precision-made binder. Fine silica powder produced after complete hydrolysis, used for the manufacture of phosphor, also used as a chemical reagent.
