Titanium Dioxide HR968

HR-968 rutile type titanium dioxide is a kind of pigment made by vitriol method．Zincoxide is used as its crystal lattice stabilizer. It is surface is treated with inorganic composite consisting of titaniuin dioxide, silica and aluminum oxide．It is coated with organic componnds Coarse powders are renloved off in production so that particle size distribution is uniforln．The product has excellent luster, outstanding hiding powder, colorability and good dispersibility. Performances of the pigment achieve or surpass that of imported similar products. The pigment is widely used in self-curing paints, some baking finishes, emulsion paints with good luster, textile printing thick liquids, leathers, printing inks, laminated cardboards and plastics.
