GB/T 21867.1-2008 《Pigments and extenders - Methods of assessment of dispersion characteristics - Part 1:Assessment from the change in tinting strength of coloured pigments》 Related products

This standard specifies a method for evaluating the dispersion of chromadizing pigments according to their tinting strength changes, which is suitable for the comparison of dispersion between similar pigments. This method evaluates the dispersion performance of pigments by comparing the tinting strength of test pigments and reference pigments under the same conditions. The test needs to be carried out in conjunction with GB/T 21868.1-2008 and is widely used in pigment production and quality control.
