Leading manufacturer and distributor of high-quality colloidal silica in various forms. We provide innovative chemical solutions with a commitment to safety, quality, and environmental responsibility.
Colloidal silica made by Violet Chem consists of dense silica particles suspended in aqueous medium. These particles are spherical and uniform in size. They do not have any internal structure of their own and are totally amorphous. These particles are discrete and non-agglomerated. Violet Chem produces colloidal silica with particle size ranging between 7 to 35 nanometers. These stable aqueous dispersions of colloidal silica are available in silica concentrations from 20 to 50 weight%.
Our colloidal silica serves as an exceptional slurry binder for investment casting shells, ensuring precise dimensional accuracy and superior surface finish in metal casting applications. Additionally, it functions as a high-performance grain binder in refractory materials including monolithic structures, gunning and ramming masses, LCC, ULCC applications, and various high-temperature ceramic products.
