SPCC POWDER COATING SPEC
SPCC POWDER COATING SPEC
(OP)
I have designed a sheet metal assembly out of SPCC steel sheet, with a few parts welded together. it may be used in a saltwater environment, and the coating should be able to handle that. I have no idea what to spec on the assembly for powder coating. I currently
spec'd powder coat polyurethane, smooth flat matte black, 0% gloss. would this be a valid spec? it will be sprayed in china, and they originally said SPCC painted black
but I want to clarify the coating and use powder coat rather than just say painting, thoughs?? or maybe like a TGIC free polyester coating maybe? and what should I spec on the drawing?

perfect cleaning
preferably zinc plating followed by
pretreatment with zinc phosphate (includes a sealer after phosphate)
thick epoxy coating followed by
thick polyurethane coating
Even with this, any small defects in the coating will lead to rapid corrosion. Most things that require resistance to saltwater exposure are either hot dip galvanized or made out of corrosion resistant alloys (stainless steels, nickel alloys, titanium, etc.).
