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.. 

Crystalline TiO2 occurs naturally in three polymorphs – anatase, rutile and brookite – among which rutile is the most stable. A powder with an average particle size of 230 nm scatters visible light, while its counterpart, with an average size of 60 nm, scatters UV light and reflects visible light. Under UV, TiO2 exhibits photocatalytic activity, which is a consequence of the electronic structure of the titania, and is, to a large extent, more characteristic of anatase than of rutile and brookite. In the presence of light with energy equal to or higher than the TiO2 band-gap energy, an electron is promoted from the valence band to the conduction band, leaving behind a positive hole. The extrapolated optical absorption gaps of anatase and rutile are 3.2 and 3.0 eV at room temperature, which correspond to wavelengths of around 413 nm and 387 nm. Consequently, the photo-activation of nano-TiO2 can be achieved by irradiation with UV-A, B and C, visible, fluorescent light, and X-ray radiation. The photocatalytic activity results in formation of highly reactive radicals, that are capable of reacting with most of the surrounding organic substances
