Test instructions:
1. Test for whiteness of oil system(L*) and Hue(b*): Grind the Titanium dioxide with grinding mill, to make a film with thickness of 100μ M. Calibrate with ASTM standard ceramic tile by Differential Colorimeter. Then test the surface of the film and indicate with CIE L*, a*, b*.
2. Test for Dispersion under high-speed mixing of Alkyd system: In the alkyd resin system, test with Scraper fineness gage after dispersion by high-speed mixer. Other items please refer to ISO standard.

Place contact with the supplier for detailed technical information of the product.
Then data in the inspection report will be the final.
