Is the surface coating technology paint on the pigment how to choose? Metal surface coating technology Pigment paint can be said to be a high quality finishes, and its metal surface color changes are to adjust the organic pigments to solve. Among the inorganic pigments, there are mainly lead and chromium, iron oxides and a small amount of cadmium pigments. The most widely used products are titanium dioxide and metallic aluminum. The following describes the color of the paint on the metal surface paint:

  Red: Preparing red metallic surface paints is a complex issue and there are many types of pigments available. The main requirement for red is a single color, that is, all colors in the range from scarlet to mid-red, blue-red and purple-tinted. Some other heterocyclic azo and condensation azo and other pigments and metal complex type pigments.

  Yellow and Orange: Among yellow-orange metallic finishes, a wide variety of monochromatic and metallic formulations are a complex issue, with a range of inorganic and organic pigments available. The most important inorganic pigments are lead chromium pigments and general and transparent yellow iron oxide. In light and middle yellow, the use of metal complex pigments makes more sense, such as C. I. Pigment Yellow 129, 17 and 153. Among all shades, universal and clear yellow iron oxide are used as matt chemicals. These oxidized pigments are economical to use and have strong durability.

  Green: Most of the green in the metal surface industry is formed from phthalocyanine green pigments. The color change of each type of phthalocyanine green depends on the degree of halogenation and the type of halogenation. So in fact their color can be changed. Phthalocyanine green pigments have the coloring properties and fastness required for coatings on metal surfaces. Phthalocyanine gorgeous green light, a strong tinting strength and excellent durability, is a full 78, fastness are good transparent pigments. Phthalocyanine green pigments are suitable for monochromatic coatings of various concentrations, but they can not be used at excessive concentrations because "copper light" is increased under exposure.
