What is the main role of talc in coating powder?

It is mainly divided into three aspects:

1. Talc powder can increase the powder coating rate and spraying area of ​​powder coatings. In addition, it does not contain heavy metals, so it is the preferred filler for powder coatings without heavy metals.

2. Talc powder acts as a skeleton in powder coatings, and their filling can increase the thickness of the coating film and improve the wear resistance and durability of the coating.

3. Talc powder can reduce the cost of coatings. Generally, the price of calcium carbonate is lower than that of other inorganic fillers. The amount of calcium carbonate added to coatings is relatively large, so adding calcium carbonate can reduce the cost of powder coatings.
