The effect of fillers on the properties of
powder coatings
Filler, also known as extender pigment, is a material with relatively low tinting power and hiding power. It's superfine, and it's a white powdery paint. This pigment is mixed in electrostatic
powder coatings and the like.
It is generally used to improve the strength and protective properties of
powder coatings. But as a filler also needs to have some conditions. The conditions of the filler are:
1. The filler is insoluble in water or some organic solvents. Generally, the filler is a material with good dispersibility and will not contain any impurities.
2. As a filler, it needs to be resistant to acid and alkali, and such fillers can be mixed in
powder coatings to better enhance the performance of
powder coatings.
3. The filler is a low-cost coating, and there are many types of fillers. For example, barium sulfate, barite powder, calcium carbonate, talc powder, mica powder, and quartz powder are often used in powder coatings. etc.
4. Different fillers have different performance advantages, which can help improve the performance of powder coatings, so that
powder coatings can better play their advantages.
