The filler has good dispersibility in thermoplastic resin and thermosetting resin.
The filler has good heat resistance, light resistance and weather resistance, does not change color during the baking process, and the coating film is not easy to powder and age during long-term outdoor use.
The filler should be non-toxic. After being added to the powder coating, it has no toxic effect on the powder coating and will not affect the health of the powder coating production and coating personnel.
There are abundant sources of fillers and the price is very cheap.

The filler varieties commonly used in powder coatings are precipitated barium sulfate, barite powder, light calcium carbonate, heavy calcium carbonate, kaolin seven, talc, bentonite, precipitated silica, mica powder, quartz powder, silica flake powder Wait. In recent years, after deep processing of these filler products, ultra-fine products of different finenesses are produced, and they are also treated with surfactants to greatly improve the dispersion of fillers in powder coatings, increase the amount of fillers, and improve the appearance of the powder coating film. Commonly used filler varieties and performance technical indicators are polytetrafluoroethylene powder dose shown in Table 2-16. The effect of filler content on powder coatings and coating films.

Additives are also an important part of powder coating formulations. Although compared with the above-mentioned resins, curing agents, pigments and fillers, their dosage is relatively small, only a few thousandths to a few percent of the total amount of the ancient formula (individual Only accounts for ten thousandths), and its effect on the performance of powder coatings and coating films cannot be ignored. In some cases, additives play a decisive role. For example, in thermosetting powder coating formulations that require a smooth and smooth appearance of the coating film, if there is no additive such as a leveling agent, it is impossible to obtain a coating film without shrinkage and other defects. The appearance of the coating film; another example is that the texture agent plays a decisive role in the appearance of the coating film.

The influence of some additives on the appearance of the coating film is shown in Figure 2-2. Although the types of additives used in powder coatings are not as solvent-based and There are many water-based coatings. However, with the advancement of powder coating technology, the variety of additives has increased significantly, and the scope of application has also been expanding. The variety of powder coatings has increased and the quality of coating films has also been significantly improved. The requirements for the types of additives required for different powder coatings are very different, but from the most basic requirements, the general powder coating additives should meet the following conditions.
