Test instructions:
1. Test for Whiteness of oil systerm ( L* ) and Hue ( b * ): Grind the Titanium dioxide with grinding mill, to make a film with thickness of 100μm. 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.
