Rutile TiO2 HTR-616
Rutile TiO2 pigment HTR-628 is coated with zirconia and alumina in an inorganicmanner and modified with special organic finishing agent on the surface. With advantages of preferred blue color, good dispersibility, low oil absorption, excellent compatibility and outstanding rheological property under processing, the pigment is particularly applicable to plastic processing. It exhibits outstanding covering power and brightness and is useful to retain the mechanical properties of the finished plastic products. It can be widely used in polyolefin, PVC, ABS, PS, section bar, plate and tube as well as color paste and oil paint.
