titanium dioxide
It is based on the experience of vitriol (Sulfuric acid) production process,combining many innovative researches such as inorganic coating,organic treatment,salt treatment,calcination control,hydrolysis,product applications and so on.
Properties
White powder,insolube in water,non-toxic,chemically extremely stable,surface treated with silicon,aluminum compounds and modified with organic compounds it has excellent pigment properites,such as high whitness,gloss,hiding poeer,tint reducing power,excellent weathering resistance and chalking resistance.
Usage
It is widely used aqueous and solvent-based exterior paints,electro-deposition paints,rubber,printing ink high quality paper,waxed paper and leathrer finishes,cosmetics,etc.
