R218、R216
General Use Rutile Titanium Dioxide
Product Description:
R218 and R216 are Rutile Titanium Dioxide pigments manufactured by the sulphate process and supplied as a fine, dry powder, which are inorganic coated with Al2O3&SiO2 and special organic surface treated to have both good optical properties and excellent pigment properties. With advanced control technology of particle-size and particular coating technology, the products show good whiteness, high gloss, great hiding power, strong tinting power, favorable weatherability , high chalk resistance, low oil absorption, good wetting and are easy to disperse in a variety of systems.
Applications:
Rutile Titanium Dioxide pigments R218 and R216 are general purpose products, widely used in industries includes indoor&outdoor coatings, interior and exterior latex paints, industrial coatings, powder coatings, road sign paint, anti-corrosive paint, antifouling paint, marine paint. The products can also be used in plastics (PVC, PE, polystyrene and polyurethane etc.), masterbatch, rubber, printing ink, leather, paper making, decoration paper and etc..
