Traditional paint coloring is to use pigment powder to directly add to the paint, or some paint manufacturers simply make the pigment into slurry, and then add it to the paint to color the paint. There are certain disadvantages in this way: for example, the color reproducibility is poor, and the coloring is uneven. Because there is no professional technology and process, the pigment particles are relatively coarse, the coloring power is not high, and the pollution is serious. When added to the coating, the light resistance and weather resistance of the coating after film forming are poor, and it is easy to fade and powdery. With the intensification of market competition, the division of labor is becoming more and more detailed, and the voice of high-end coatings is getting higher and higher. In the 1990s, domestic color paste manufacturers came into being. At the beginning, there were one or two manufacturers specializing in color paste; In fact, in foreign countries, there were specialized color paste manufacturers in the 1960s, and some famous brands such as Clariant, Degussa, Hibiscus, etc. At that time, some domestic paint manufacturers with strong quality awareness began to buy color paste from abroad, but the price was relatively high, such as iron oxide series color paste, at that time, the price was even as high as 100 yuan/kg, Later, domestic color paste manufacturers rose, and the price also fell relatively, from more than 30 yuan per kilogram to more than 10 yuan per kilogram. On the one hand, it is the improvement of technology and equipment, and the cost is controllable; Second, the competition is becoming more and more fierce, and some manufacturers have reduced their profits. Nevertheless, the quality of color paste products has improved a lot compared with that at the beginning, and the varieties have also been improved. There are also one or two color paste manufacturers at the beginning, and now there are twenty or thirty, mainly distributed in Jiangsu, Zhejiang, Shanghai, Guangdong and other places.
