pigment performance characteristics

Color. Color pigment is a selective absorption of the visible light and scattering pigment,
 Acrylic paint
In natural light conditions, showing yellow, red, blue, green and other colors.
Tinting strength. The yellow iron oxide  ability to absorb the incident light colored pigment. Can be equivalent to the standard sample coloring pigments relative percentage.
Hiding. In the film-forming material covering the substrate surface color capability. Used to cover one square meter area contained in paint pigment expressed in grams.
Lightfastness. Under certain light pigment colors maintain its original performance. System generally use eight said butyl stearate  eight best.
Weatherability. The pigment in a natural or artificial climatic conditions, to maintain its original performance capability. Generally use five system, said five best.
Volatiles. Mainly refers to the water, generally shall not exceed 1%.
Oil absorption. Means to form a homogeneous mass 100 g pigment refined required grams of linseed oil, with oil by a small amount of good oil absorption of the pigment particles have a specific surface area and structure.
Water soluble. Pigments containing water soluble substances, in order to account for the quality of the  PVC heat stabilizer pigment expressed as a percentage. Paints with paint, water-soluble material which normally control in 1% or less.
