- To get rid of pinholes in powder coating, is it only possible to use benzoin?

- No, wax also eliminates pinholes and is less prone to yellowing!

Why do powder coatings easily form pinholes?

Powder coatings are mainly applied by electrostatic spraying

What is the difference between benzoin and degassed wax?

There are different opinions on the degassing mechanism of benzoin in the industry.

The key to the use of degassed wax is the film-forming stage of thermal curing of the coating, that is, the stage where the powder particles are heated from a solid state to a liquid phase, and then cross-linked and cured

For a comprehensive consideration of economy and effect, we recommend using benzoin and degassing wax together to achieve the best effect!
