(NPR) Skydrol Resistent paint

Post by blackeagle603 »

A question came up from an acquaintance in the avionics design/test business (think he's at Rockwell/Collins currently). Customer has a requirement that paint be able to hold up under exposure to Skydrol. Probably as part of a callout for FAA DO-160 and of the equivalent mil spec (either 883 or 810).

Are polyurethane enamels (e.g. Imron) still a thing in common use? Nasty (and beautiful).

Long time since I exercised my A&P license or spent time in the paint hanger. Need to check in with youz aviation maintenance types and see what's commonly in use these days.

The Boeing spec is a polyurethane, and it still holds up only just so long when exposed to skydrol. The epoxy primer is BMS10-11 but I don't recall off the top of my head the spec number for the topcoat. At work we use Akzo Nobel Eclipse but last I heard Boeing was using a PPG product for factory paint jobs.

No problem. FWIW the stuff Boeing uses gets stained from oil, dirt, etc. Haven't seen that problem with the Eclipse.
