Test instructions

  1. Test for whiteness of oil systerm(L*)and Hue(B*):Grand 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 ISOstandard.
