Influence of filler on properties of thermosetting powder coatings explained by plastic powder manufacturer

Plastic powder manufacturers explain the effect of fillers on the properties of thermosetting powder coatings.

What is filler and its effect on powder coatings? Believe that many people are not clear, filler is also known as the physical pigment, is a coloring force, covering force is relatively small material. It is a super fine type, or a white powder coating. This pigment is mixed in electrostatic powder coating and so on.

It is generally used to improve the strength and protective properties of powder coatings. But as filler, it also requires some conditions. The conditions of packing are as follows:

1. The filler is insoluble in water or some organic solvents. Generally, the filler is a well-dispersed material and does not contain any impurities.

2. As a filler, it is necessary to be able to resist acid and alkali, so that the filler can be mixed in powder coatings to better enhance the performance of powder coatings.

3. Filler is a kind of low-cost coatings, filler types are more, such as powder coatings are often used barium sulfate, barite powder, calcium carbonate, talc powder, mica powder, quartz powder and so on.

4. Different fillers have different performance advantages, can help to improve the performance of powder coatings, powder coatings can play a better advantage.
