Powder coating question.
 

I'm not sure which forum is best for this question.

I'm wanting to powdercoat a steel frame bicycle. I applied JP Weigle Frame Saver to the frame
last year. My question is, how will the Frame Saver react to the heating process of powercoating. Should
it be removed prior to powdercoating. If so, how should it be removed. I'm just trying to think ahead to
avoid problems.

Thanks!

Framesaver is basically linseed oil, it will be fine. The powder coater should prep the frame before hand and remove any external grease anyway.

Just ask the powder coater.

It it's a problem, you could flush the inside of the frame with a solvent or hot soapy water.

I don't think there's any practical way to clean inside of frame prior to PC. Simply re-treat frame after PCing (oven baking may not actually hurt frame protection much, but it's simple to re-treat just to be sure).

Go to walmart, buy a lifetime supply of boiled linseed oil in paint dept. for $5 (1 qt). This is enough for 5 frames if you're wasteful, or more if neat.

After PCing frame, pour BLO into frame tubes, slosh around to fully coat all inner tubing walls. Plug holes with paper towel to aid in this process and reduce mess. Do DT,TT,ST, HT,stays.

Hang frame over old newspaper (ideally outside for smell), let excess BLO drain. Wipe it off external surfaces before it hardens, very difficult to remove once hardened, akin to sticker adhesive residue. Change orientation of frame often to get all the free BLO out of frame.

It will stink for about a week, at which point the BLO will have dried, and you can begin to build frame.

You can also use extra BLO as a cheap threadlocker (works good on spoke threads for wheelbuilding).

DANGER!!!
Keep in mind that Linseed Oil-soaked rags can and *WILL* spontaneously combust in not handled properly!! Read the directions for proper disposal.

will powder coating weaken a chromoly frame, weather its the eloctrostatic charge, or the heat process?

no the temperature are too low to do any damage to the steel.
Curing temperature are 180-200 Celsius for 5- 10 minutes and the electrostatic charge aren't that high.
