Powdercoating Specifications
Powdercoating Specifications
(OP)
I am sending some parts out for quote. They will be mounted on the exterior of the aircraft. What is the most common powdercoating conventions for exterior parts? Color will most likely be white. I have accounted 0.010 globally for coating thickness.
Any direction is greatly appreciated.
Cheers, UgLay.

RE: Powdercoating Specifications
Of course, that doesn't hold true for anything hat has to transmit/receive. Antennas shouldn't be touched due to transmissivity requirements. Antenna support structure should have the same coating system as the fuselage for the reasons I mentioned above. You also have to consider electrical bonding of the antenna to the airplane. Will a powder coated doubler affect bonding?
To answer your question, MIL-PRF-24712 is the only standard I'm aware of. Powder coating is entirely dependent on the facility and equipment.

with any discontinuity (even a thin corner) it can trap moisture underneath, kids' playground equipment shows that.

I sent out some files to a couple of machine shops and they are not really sure what to do about the MIL-PRF-24712 specification.

I would investigate the coating system on the tailcone - fuselage interface (if the fuselage is aluminum) and copy it.

I'll look in the SRM and see what kind of specs I find for existing finish.

The matter at hand is the powder coating, not any of the technical aspects that an ELT antenna install require.
