Can you paint on top of Aluchrome

2006

I am having trouble with paint adhesion on Aluchrome parts.
My sub contract paint plant tells me that it is very difficult to obtain good adhesion on top of Aluchrome.

Is he telling me all.

Hi Peter. He may be telling you all he knows, but he is not telling you all.

Chromate conversion coatings are the "standard" for prepaint treatment of aluminum. Like anything else, they need to be done right; right for pretreatment application can be different than right for final finish.

For one thing, the chromate for pretreatment must be very thin so it won't shear off. Good luck.
