Hello, would you like to ask about the curing hardness of nano-silica sol? Nanosilica sol has very strong curing hardness. Uses of silica sol:

1. Used as a binder for various refractory materials, with strong adhesion and high temperature resistance (1500°C-1600°C).

2. Used in the coating industry, it can make the coating strong, anti-fouling, dust-proof, aging-resistant, fire-proof and other functions.

3. Used for thin shell precision casting, which can make the shell strong and the casting smooth. Using its molding quality is better than water glass molding, and replacing ethyl silicate molding can reduce costs and improve operating conditions.

4. Silica sol has a high specific surface area and can be used for catalyst manufacturing and catalyst carrier.

5. Used in the paper industry, it can be used as cellophane anti-sticking agent, photographic paper pre-treatment agent, cement bag anti-slip agent, etc.

6. It is used as a sizing agent in the textile industry. It is used together with oil agents to improve the spinnability of wool and rabbit hair, reduce breakage, prevent flying flowers, improve the yield of finished products, and increase economic benefits.

7. Used as silicon steel sheet treatment agent, picture tube dispersant, floor wax anti-skid, etc.
