Product Desciption

Characteristics
Silica sol is a colloidal solution, odorless, non-toxic, with a large specific surface area between particles, colorless and transparent, and does not affect the true color of the covered material; low viscosity, strong penetration ability, and good dispersion performance; when the water evaporates , The colloidal particles form a combination of silicon and oxygen and firmly adhere to the surface of the object. It is a good adhesive.

Use
1, Used as a binder for refractory materials, with strong bonding power and high temperature resistance of 1500-1600 degrees.
2, It can be used in the coating industry to make the coating firm, anti-fouling, dust-proof,         anti-aging, and fire-proof.
3, For precision casting, it can make the shell strong and smooth.
4. Used as cellophane anti-adhesive, photographic paper pretreatment agent, cement bag anti-slip agent, etc.
5, Used as silicon steel sheet treatment agent, battery electrolyte, kinescope dispersant, floor       wax anti-slip agent, etc.

Size
Divided by content: 20%; 25%; 30%, etc.
