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 100I 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.
