The classification of the pigment is recognized method, the reason is that paint variety, chemical composition difference is very big, use is various, so according to what kind of classification methods are not ideal.
More common classification method is in accordance with the paint chemical composition will be divided into inorganic pigments and organic pigments. Tell from the performance, inorganic pigment fast, heat resistant performance is good, strong hiding power, but not very complete chromatography, tinting strength is low, poor color brilliance, toxicity of some metal oxides and salts. Organic pigment structure variety, complete chromatography, color bright, pure tinting strength is strong, but light resistance, weather resistance and chemical stability, the price is more expensive.
Fluorescent pigment is divided into inorganic fluorescent pigment (such as fluorescent lamps and fluorescent ink anti-counterfeiting with) with fluorescent dye and organic fluorescent pigments (also known as daylight fluorescent pigments) : only on the chemical structure of certain substance will have fluorescent properties. But these fluorescent colorant itself often in the light, which has inherent problems, solvent resistance and other properties. A method to overcome the deficiency of is, will they by chemical or physical method fusion into the structure of polymer materials, and then further processed into paint. Polymer materials used for this purpose, both have fluorescent stain of the solvent effect, but also provides protection for the fluorescent stain, granting the fluorescent stain better properties, such as light resistance and solvent resistance.
