First: powder paint powder color commonly used pigments
Pigments used in powder coating powder can usually be classified in different ways according to production method, composition structure, function, etc.:
According to the production method, the production method can be divided into natural pigments and synthetic pigments, natural pigments such as ingot green, generally used in powder coating powder in the natural pigments, and synthetic pigments are titanium dioxide, iron oxide pigments, phthalocyanine series, azo pigments, polycyclic pigments, etc.
Functional distinction, according to the function in powder coating powder can be divided into coloring pigments, constitution pigments (also known as filler), rust pigments, conductive pigments, etc., For most functional powder coating powder, the application of functional fillers is very important.
According to the chemical composition structure, powder coating powder pigments can be divided into inorganic and organic according to the chemical composition structure, inorganic pigments in titanium dioxide, zinc oxide, iron oxide series, molybdenum chromium series, aluminum pigments, metal pigments, and organic pigments such as phthalocyanine series, azo series, polycyclic pigments, etc.
Second: due to the limitations of computer color measurement of powder coating powder, artificial color matching is now particularly important. Conditional manufacturers can do some database, monochrome plate system experiment for a pigment, and make three color levels for a given pigment: less or no white pigment with high saturation color plate; a light color swatch diluted with a large amount of white pigment; a dark color swatch with black paint.
