Paint tinting strength refers to a certain amount of pigment color products required, expressed as a percentage with standard samples of tinting strength.

Tinting strength not only with properties of pigment, but also related to the pigment dispersion degree. Pigment dispersion degree is mainly refers to the degree of refinement, the greater the dispersion degree, the degree of coloring shu is high, but there is a maximum, tinting strength decline more than this value. Azo pigment particle size in, for example, 0.1 mu m, phthalocyanine blue pigment particle size around 0.05 mu m, the highest tinting strength.

Plastic with pigment color standard sample and sample standard recommended adding different amount of resin, at the same depth ratio, namely A for the standard color plate to add resin, B is similar to A color depth of adding amount of resin.
