Product Description:
R218 is Rutile Titanium Dioxide pigment manufactured by the sulfate process and supplied as a fine, dry powder, which is 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 product shows good whiteness, high gloss, great hiding power, strong tinting power, favorable weatherability, high chalk resistance, low oil absorption, good wetting and is easy to disperse in a variety of systems.
Applications:
Rutile Titanium Dioxide pigment R218 is general purpose product, widely used in industries including indoor&outdoor coatings, interior and exterior latex paints, industrial coatings, powder coatings, road sign paint, anti-corrosive paint, antifouling paint, marine paint. The product can also be used in plastics (PVC, PE, polystyrene and polyurethane etc. ), masterbatch, rubber, printing ink, leather, paper making and decoration paper, etc...
