Colloidal silica is the watery dispersoid of silicon dioxide. Its molecular formula can be mSiO2 - nH2O. It can be widely used in industrial productions, such as investment casting, vacuum-formed fibrous shapes, refractory materials, inorganic coatings, stool and mold coatings, textile industry, paper and film making, hot-top insulating boards, catalyst binders and supports, treatment of carbon products, and enhanced foam rubber. It has been also used as water-purify agent, clarification agent, polishes, reinforcing agent, and molecular sieves.
We are manufacturing high purity colloidal silica in concentration from 15% to 40%, with or without alkali, and particle size varying from 5nm to 120nm. There are several kinds of colloidal silica in our company: In addition, we can also manufacture special colloidal silica as per customers' requirements. |
