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 CIEL*,a*,b*.

2, Test for Dispersion under high-speed mixing of Alkyd system: ln the alkyd resin system,

test with Scraper fineness gage after dispersion by high-speed mixer. Other items please refer to

ISO standard.
