Test instructions

Test for whiteness of oil systerm( L* ) andHue( B* ) : Grind the Titanium dioxide with grinding mill.to make a film with thickness of 100¼ m.Calibrate with ASTM standard ceramic tile by Differential Colorimeter.Then test the surface of the film and indicate with CIE L* , a* , b*
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 ISOstandard.
