It is very suitable for powder coatings: Conagar yellow and Connor chromium series inorganic pigments are suitable for powder coatings. The specific pigment varieties are shown in Table 2-4. Organic pigments such as Dan-resistant pigments and Palio to l series: Sicom in series, Sic opal series, Sic otan series, Palo tan series, Sico trans series and Palio er on effect pigments and other inorganic pigments can also be used in powder coatings. The specific pigment varieties are shown in Table 2-5. According to the performance of the tax pigments, combined with the technical index requirements of the coating film performance of the powder coatings, the picking varieties that can meet the performance requirements can be selected. The models and specifications of aluminum pigments (powders and pellets) for powder coatings of Aika, Schlenk and Toyo Aluminum are shown polytetrafluoroethylene powder cas number in Table 2-6; the models and specifications of gold powders for powder coatings of Aika and Schlenk are shown in Table 2 7; The model and specifications of aluminum powder for powder coating produced by Changsha Zuxing New Material Co., Ltd.: The model and specifications of aluminum powder for powder coating produced by Shandong Zhangqiu Lubang Chemical Co., Ltd. are shown in Table 2-9. Pearlescent pigment model And specifications.

The influence of the content of pigments and fillers in powder coating formulations on the properties of powder coatings and coating films is shown in Figure 2-1. It can be seen from the figure that the content of pigments and fillers in powder coating formulations has a great impact on the various properties of powder coatings and coating films. Therefore, to obtain the ideal powder coating, not only the types of pigments and fillers, but also the amount of them must be selected. The amount of pigments and fillers added varies with the types of resins. Generally, they have good dispersibility in thermosetting powder coatings, and the amount of addition is large.

The order of addition amount is: polyester resin>epoxy resin>acrylic resin. Taking titanium dioxide as an example, when the addition amount of polyester powder coating is 40% by mass, the coating film is shiny and smooth: However, when the addition amount of acrylic powder coating exceeds 20%, the film gloss is not high, and the physical mechanics Performance is significantly reduced. In addition, the amount of pigment and filler added is related to the dispersion method. Generally, the dispersion effect of 30 melt extrusion mixing method is good, and the dispersion effect of dry mixing method 20 is poor.
