Improved Hiding Power

Figure 1: Ti-Pure™ R-902+ Delivers Total Value*• Better coating coverage

Alkyd Dispersibility• Minimum TiO2 use in coatings formulas
Ti-Pure™ R-902+ provides exceptional hiding power andtint strength in a wide variety of coating formulations.
As shown in Figure 2, our extensive testing has shownthat Ti-Pure™ R-902+ consistently outperforms
multi-purpose grades from global competitors.
The exceptional dispersion and unique particle size
distribution of Ti-Pure™ R-902+ is the key to excellent
optical performance. Using Ti-Pure™ R-902+ will provide
excellent coating coverage and may allow coatingproducers to reduce your coating raw material costs by
reducing the amount of TiO2 in the paint.

advantage of Ti-Pure™ R-902+ relative tocompetitive grades. It also highlights theopportunity for productivity improvements andenergy savings from using Ti-Pure™ R-902+
As alkyd dispersion time and intensity are increased
the dispersion condition is evaluated using a special
hegman gauge. Dispersion condition is analyzedusing the Chemours™ Dispersion Optical Counter(DOC) which takes a digital image of the drawdown
and uses proprietary protocol to measure thenumber of undispersed particles.
The results show wide variation in how different
TiO2 grades disperse following the various grindconditions. While most pigments require the highest
grind intensity (5 minutes at 12 m/s) to achievea clean dispersion (<10 undispered particles),Ti-Pure™ R-902+ achieves a clean dispersion withmuch less time and energy.
