Re: (ET) Powder coat colors



Some more info:

RAL 3011 is a very nice match to the Wheelhorse red
(lists at $6.75/pound from DuPont, 25 pound minimum)

RAL 2002 or RAL 2012 is somewhat similar to the orange (I-5?? or New Idea??). "Steel rack orange", a stock color from Tiger Drylac, looks like a closer match to me.

For the ET yellow, there is no good RAL color match. RAL 1004 may be the closest or maybe 1032, but again these really aren't that close at all. After looking at the RAL colors, the GE yellow looks so dull that I'm tempted to use something like RAL 1004 for a more pleasing looking tractor, but then the purist in me thinks that getting the custom color to match would be a better idea. I'd be curious what other people think?


For those wondering about the "RAL"... it is a European color standard, so that RAL 1234 from DuPont or Tiger Drylac or any other manufacturer will always be the same. It is also the same for different mediums of powder, paint, etc. I suspect the RAL colors are more consistent than the tractors paints were 35 years ago, and are certainly more consistent than the tractor colors are now as no two ETs look alike today - even those always stored indoors.

If I understand correctly, 1 pound of powder covers ~30 square feet. Unfortunately the yellow/orange/red end of the spectrum is the most expensive. The manufactures like to point out that these colors were once made with various heavy metals (ie cadmium was likely in the ET yellow) and now other materials must be used.

I have looked into powder coat colors as well...

There is no standard RAL yellow that remotely matches and I have yet to find any stock yellow that comes close. So, I am considering getting a custom powder mix. If I were to do so, would others want to buy some of the powder? You would either need the application equipment and oven to apply it yourself, or take it to a local shop. In very general terms, standard colors in small quantities are < $5/pound. The custom color would likely be $10 to $15/pound.

For the red and orange, there are standard colors that are a reasonable match. I will find my notes and post the details shortly.

epoxy powder coat will "provide excellent resistance to 40% solutions of sulfuric acid". According to my info, that should about the concentration of battery acid.

If I ever get my powder coating oven finished, it will be big enough to cure the entire frame box of an E8 / E10 small frame ET. I have a parted out New Idea EGT100 frame box that is in really good shape that I may try to powder coat.

BTW, does anyone know the RAL number for the powder that most closely matches GE yellow, or Wheel Horse red, or New Idea orange?
