How do apply wrinkles powder coating

The key to a good wrinkle is preparation. Have a good pre-treatment system in place. No matter if you shot blast or use chemical pretreat, keep it consistent across the board. Clean all contaminants, especially oil, from the part and ensure the pretreat is applied evenly as any dirt or contaminants can interfere with how the wrinkles form.

Next, depending on whether you use a batch oven or automatic system, you need to be sure that it is a conventional fire oven. You need to be able to ramp up the temperature quickly at the start of the cure cycle to ensure consistent wrinkling in the coating. In our general experience working with wrinkles in an infrared oven can be extremely tricky and is best avoided!

As for the actual application, it applies like any other powder. The trick is to settle on a film thickness that achieves the effect you and your customer want, as a thinner film may not wrinkle to the same degree as a thicker film. Be certain to always refer to the Technical Data Sheet for accurate thicknesses and cure times.
