Coating selection help
(OP)
Hi all,
I am making an electrical enclosure for an industrial shop type environment. For the outside aluminum panels we currently use e nickel and then paint the visible outside portions. The e nickel was selected because it has good corrosion resistance and electrical conductivity, both of which we need. The outside paint doesn't bond too well to the e nickel.
For the next run of parts we would like to use powder coat instead of paint to be consistent with our other products as well as painters are getting harder to find in Ca. I'm worried that the powder coat will also have a bonding issue with the e nickel. I was considering switching the e nickel to alodine as alodine is also electrically conductive as well as corrosion resistant. Alodine also makes a great base for painting. The issue is that I have been reading that alodine breaks down at high temperatures which the part will experience during the powder coating curing.
Does anyone have any suggestions to accomplish my needs?
Thanks in advance for your time.

2) Do you have to actually plate/paint the enclosure? Aluminum can be pretty nice on its own, or anodized.
3) If you want a durable coating on aluminum, you can specify a coating system which has passed AAMA 2605 at an independent lab. Generally this will be a fluoropolymer system.

Thanks for responding.
Yes we have to powder coat the outside (visible) surface of the panels while the inside must be electrically conductive as well as corrosion resistant.

The deck is 6-10 feet off the water depending on the tide, and the panels are 2-3 feet higher.
