Silicon dioxide polishing solution
Product description
The product is an alkaline silica dispersion with strong lubricity, which will not be affected even if it condenses. Colloidal silicon products with the highest precision are suitable for precision hardware, silicon, sapphire and other kinds of oxide crystals. The recommended dilution ratio with deionized water is 1:1, and the pH value is 9.5-11.5. It is used in combination with \450 asphalt or LP polyurethane polishing leather.
