750Y High Pore Volume Coating Silica Matting Agent
High Surface Area, High Pore Volume, Good Matting
Chemical Properties
White powder forms superfine silica, which is made by specific sol-gel method process. It can be dissolved by NaOH, HF. Other kinds of acid, water and organic solvents cannot dissolve the product. Resistance to high temperature, no combustion, good insulation, odourless and good extinction properties.
