Description:
1. White powder
2. Titanium dioxide occurs in nature as well-known minerals rutile and anatase.
3. Chemical stability, insoluble in water, organic acid and inorganic weak acid, soluble in oil of vitriol, alkali and hydrofluoric acid.
It is Widely used in aqueous and solvent-based exterior paints, electro-deposition paints plastics, rubber, printing ink, high quality paper, waxed paper and leather finishes, and cosmetics
