Ethyl Silicate 40, also known as ethyl polysilicate or simply "ES-40," is a specific type of ethyl silicate compound. It is characterized by having an average of approximately 40% silicon dioxide (SiO₂) content by weight. Ethyl Silicate 40 is composed of silicon (Si) bonded to ethoxy groups (C₂H₅O-) and is commonly represented by the chemical formula Si(OC₂H₅)₄.

1.Adhesion promoter for paint coatings, investment casting materials and ceramic materials; crosslinking agent for silicone rubber.
2.Ethyl silicate can be used as insulating materials, coatings for the electronics industry, zinc powder coating binders, optical glass treatment agents, coagulants.Organic silicon solvents and precision casting binders for the electronics industry, and to manufacture models for metal investment casting methods box.
3.After the ethyl silicate is completely hydrolyzed, extremely fine silicon oxide powder is produced, which is used to make phosphors.
4.It is used for organic synthesis, preparation of soluble silicon, catalyst, etc..
5.It is also used as a crosslinking agent and intermediate in the production of polysilicone.
