Please someone help me!?
My problem: Outgassing on diecast aluminum parts.
We are powder coating a diecast aluminum part that has been milled/sanded on one side. That side is the only area we experience the outgassing on. I understand that the milling/sanding is creating our problem but we are kind of stuck with it. We have tried pre-curing the diecast parts (helps a little). We have also tried an additive to the powder (OGF), which by the way did eliminate the outgassing. but also dulled the finish of the powdercoat (unexceptable) which unfortunatly is Tiger Drylacs' Extreme Chrome which is a very reflective/gloss powder. This particular powder is the only color we experience the outgassing on & we spray about 40 different colors. Is there an additive that could be added the the cleaning process (rinse take for example)? We have a 5 stage washer 1st stage alkaline cleaner, 2nd stage rinse, 3rd stage phosphate, 4th & 5th stage rinse.
Thanks for any and all suggestions.
