China Rutile Grade Titanium Dioxide R218

Name of Commodity: Rutile R218
Description: R218 is the Aluminium & Zirconium modified rutile pigment produced by the sulfate process. It is a kind of multi-purpose white pigment. Precise process control, good particle size and particle size distribution make it have high gloss, bluish undertone, superior tinting strength. Special surface treatment technology provides the product with the characteristics of high weathering resistance, lower oil absorption, easy dispersibility. Therefore, it is widely applied to the areas of paints, rubber, leather and printing ink, etc.
Applications:
Suitable for high-grade indoor coatings, high solid-content paint, powder coating, road sign paint, special paint for ships and printing ink. Also used in plastics(PVC, PE, polystyrene and polyurethane etc. ), rubber, paper making and leather industries, etc.
