Default Re: I guess I'm doing something wrong....

Looks like to much powder (orange peel). Below is from Tiger Drylac Troubleshooting.

Powder coat layer shows uneven surface prior to curing, after curing shows orange peel, wavy flow, or pinholes.
Possible causes & Corrections

Parts are too hot coming from dry-off oven Allow longer cooling time (less than 40 [°C] / 104 [°F]) for parts

Preheat temperature too high - Lower preheat temperature or allow for cooling (less than 40 [°C] / 104 [°F])

Powder flow too high - Lower powder feed

Coating time too long Lower coating time

Unfavorable geometry of parts Change hanging or gun configuration
Gun-to-part distance too close Increase gun-to-part distance
