Ethyl silicate CAS 78-10-4 Tetraethyl orthosilicate (TEOS) Россия

Structural formula:

Product Description：

Ethyl silicate, with the chemical formula Si(OC2H5)4, is a colorless and transparent liquid. It is widely used in many industrial fields for its excellent physical and chemical properties. As a multifunctional chemical raw material, ethyl silicate plays an important role in heat-resistant coatings, chemical-resistant coatings, semiconductor manufacturing, and precision casting.

Product Features:

Chemical properties: Ethyl silicate has high reactivity and can react exothermically with acids. Under the action of strong oxidizing acids, it may cause exotherm to ignite the reaction products. In addition, it can also react with corrosive solutions, alkali metals and hydrides to generate flammable hydrogen.

Physical properties: Ethyl silicate has a melting point of -77°C and a boiling point of 165.5°C. It is slightly soluble in water and easily soluble in ethanol and ether.

Main uses：

1.Coatings and coatings: Ethyl silicate is widely used in the preparation of weather-resistant and chemical-resistant coatings. These coatings can not only improve the durability of the product, but also provide excellent protective properties.

2.Precision casting: In the casting process of high melting point alloys and copper alloys, ethyl silicate is used as a binder in the "lost wax" process to effectively improve the precision and quality of castings. In addition, it is also used for casting dental restorations.

3.Building protection: As a preservative for stone, bricks, concrete and gypsum, ethyl silicate is widely used in waterproofing, windproofing and acid-proofing processes, which can effectively extend the service life of building materials.

4.Electronics and semiconductor manufacturing: Ethyl silicate is an important precursor for the preparation of silicon dioxide films in chemical vapor deposition (CVD), and is used as an insulating material and optical glass treatment agent in the semiconductor manufacturing process. Applications in the semiconductor and electronics industries

5.Heat-resistant and chemical-resistant coatings: As a base material for high-performance coatings, ethyl silicate is used to make heat-resistant and chemical-resistant coatings, and is widely used in protective coatings for industrial buildings and castings.

6.Silicone synthesis: Ethyl silicate is one of the main raw materials for silicone solvents.
