Product description
R6638
R6638 is a silicon, aluminum inorganic and organic surface treated rutile titanium dioxide, it has a uniform particle size distribution, good water dispersion, good hiding power and high weather resistance properties. It is mainly used in water-based system which demand high water dispersion, such as paper-making, water-based coating(especially interior and exterior emulsion paint), and water-based ink production.

How to select a pigment grade
Request the current technical data sheet (TDS), safety data sheet (SDS) and the available batch inspection report or certificate of analysis (COA). Compare TiO2 content, whiteness, oil absorption, dispersion and other parameters relevant to the intended application.
Selection guidance is a starting point. Final specifications depend on the supplied grade and batch inspection report.
