What is Ethyl Silicate?
Ethyl Silicate is a chemical compound with the molecular formula C8H20O4Si.
Properties
Ethyl silicate series chemical composition general formula: (C2H5O)2n+2SinOn-1
It is colourless or light yellow transparent liquid at room temperature, with the smell similar to ether, can be mutually soluble with organic solvents such as ethanol, acetone, etc. It can hydrolyse with any water to generate silicate sol and release heat, it becomes turbid in humid air, and clarifies after standing, non-toxic.
Use: With the continuous development of science and technology, the application of ethyl silicate series products will be more widely used, especially the melt mould precision casting so that its process has the superiority of application.
- All alloy castings can be manufactured, especially heat-resistant and high hardness alloys that are difficult to machine.
- Because there is no parting surface, so the casting surface quality is high;.
- The casting dimensions are extremely accurate and the surface finish is high, which greatly saves metal materials and processing costs.
- Can cast a variety of complex shapes of the moulding parts;
- A variety of fire-resistant binder
- It is the best material for manufacturing high-grade, anti-corrosion, sunscreen and permanent paint.
To sum up, ethyl silicate series products in many sectors of the modern national economy, such as aviation, ships, automobiles, tractors, machine tools, agricultural machinery, turbines, telecommunications machinery, instruments, cutting tools, weapons and other manufacturing industries, by domestic and foreign users and technical experts fully affirmed, will be more and more widely used.
Production Methods
Batch, semi-continuous and continuous production methods are commonly used in the industry. Diagram of batch production.

This product is mainly used as hydrolysate binder in ceramic mould precision casting, ethyl silicate itself is not a binder. It must be hydrolysed to become hydrolysate to have bonding ability, therefore. The so-called ethyl silicate binder refers to the hydrolysis of ethyl silicate in the investment casting industry, coated with soluble model on the special refractory materials, is made of ethyl silicate hydrolysis and powdered refractory materials, formulated.
The aqueous solution of ethyl silicate, is the reaction between ethyl silicate and water, is essentially the process of ethoxy (-C2H5O) in the ethyl silicate molecule is replaced by hydroxide (-OH) in water, specifically, this process is the whole process of the reaction of ethyl silicate with water through the action of the melting agent (ethanol) and catalyst (hydrochloric acid).
Caution.
Although ethyl silicate series products are non-toxic, but after all, it is a chemical raw material, so it should be avoided contact with the skin or enter into the body, if it happens, it should be washed with water.

The product silica content is higher than the industrial ethyl silicate, such as for the production of strength characteristics of the same castings, ethyl silicate dosage will be reduced accordingly, can reduce costs, foreign investment casting mainly with the product. The product is also the production of high-quality, sea-going anti-corrosion silicone paint the most advanced raw materials. The use of the products produced by the paint has anti-corrosion, sunscreen. Rainproof, gloss and other characteristics.
