Features of High-grade Silica Sand
 
Through chemical blanching and the superfine processing from the super purified and high-quality natural silica ore
 
High pure white color, good gloss, anti-corrosive, anti-acid, and anti-alkali.
 
The best filling materials and additives in comprehensive applications include paint-coatings, adhesives, sealants, silica gels, epoxy resins and etc.
