Copperhead Posted June 11, 2007 Share Posted June 11, 2007 Does anyone have a recommendation for an accurate chromate yellow color? There seems to be a good deal of variation between manufacturers, and none that I have looked seem to match period photographs very well. All replies appreciated.

ChrisS Posted June 11, 2007 Share Posted June 11, 2007 Polyscale Zink Yellow or maybe its Yellow Zink...? That's what I use all the time, looks fine to my eyes. Link to comment Share on other sites More sharing options...
Gene Posted June 11, 2007 Share Posted June 11, 2007 Hi Coppehead! Using more enamels, I'm not familiar with Chris's Polyscale, but I'm sure it's a good choice. I've found in enamels the following Model Master and Testors paints. (The Grey and Interior Green are included for reference - all shot on 'white' paper) HTH: Link to comment Share on other sites More sharing options...
tourist Posted June 11, 2007 Share Posted June 11, 2007 Hi copperhead, Chromate yellow wasn't a color, just chromate zinc. It's color was variable from the almost fluo greenish to the warm pale yellow. Anyone who lived in the 30's, 40's or 50's has seen that stuff. In other words, you can't go wrong with any of the available paints, they're different but all correct. Link to comment Share on other sites More sharing options...
Craig361 Posted June 11, 2007 Share Posted June 11, 2007 tourist is correct about the chromate zinc, the baby poop yellow is it's natural 'color'. Everything else is a dirivetive of adding something to it to get another 'color'. Such as adding lamp black to chromate zinc to get green chromate zinc etc. Link to comment Share on other sites More sharing options...

Norm Posted June 12, 2007 Share Posted June 12, 2007 As mentioned above, It is not really a color, but a specific mix of Zinc powder with a carrier agent, usually clear lacquer. There were specific ratios for different applications. As a side note, Boeing specified that the apple Green colored primer be used in areas exposed to the elements such as wheel and flap wells, and the Yellow colored stuff was for areas sealed from the outside weather, like fuel cells inside wings. That implies that the "exterior" material may have had some other additive to protect the coating. As a side note, if you mention Zinc Chromate primer to a railroad modeler, he thinks of a very dark maroon primer. Norm Link to comment Share on other sites More sharing options...
LDSmodeller Posted June 12, 2007 Share Posted June 12, 2007 Hi Copperhead Welcome to LSP Ditto to comments already made, it also depends on what type of aircraft your building and era http://www.ipmsstockholm.org/magazine/2004...rs_us_part2.htm If you have a read through this article, it will be of immense help to you. To answer your original question, I like using Humbrol so a good match for "Zinc Chromate Yellow: is Humbrol 81 (pale yellow) If you want the apple green type or Interior Green: Humbrol 151 Interior Green HTH Alan Link to comment Share on other sites More sharing options...
