Colouring sheet/folded metal
Colouring sheet/folded metal
(OP)
Folks,
I am working with a client company who currently buy in a folded enclosed sheet metal panel that is foam filled for insulation purposes. The company buys the panels coloured and has limited colour options on the metal and would therefore like to buy the panel uncoloured and colour themselves to any colour/shade/RAL number.
The problem the company has is that if it tries to powder coat the panels, the heat generated during powder coating melts the foam. We are investigating to see if the supplier can supply said panel with a higher melt temperature foam.
I would however welcome alternative suggested solutions to the problem preferably solutions that do not include spray/painting as the panels are large and the company isn't set up for it.
Thanks in advance.

However, at least some of them are kind of 'heat shrunk' so not sure it would help.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
RE: Colouring sheet/folded metal
There are a number of different "paint" options: some require moderately elevated temperature for curing (~ 100 C), some require higher temperatures than that (powder coat, 190+ C), and some are air drying. Formulations based on alkyds instead of epoxy, polyester, polyurethane are usually capable of air drying. Here are some links to example products:
