Silica is a natural compound of silicon and oxygen mostly found in sand, Silica has three main types of crystals: quartz, tridymite and cristobalite. Blue silica gel is silicon dioxide with large pore diameter and high moisture adsorption capacity. It has a moisture retention feature of more than 35% by weight. The color change is from blue to pink.

Application

» Color changing (indicator) silica gels are used especially in transformers, oil tanks and vents of chemical tanks.
» This substance is widely used in coating products, inks and toners, adhesives and sealants, lacquers, putties, plasters, modeling clay, cosmetics and personal care products, washing and cleaning products, and pharmaceuticals.
