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 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.
