best air temp

Well Known Member
The Dupont Variprime tech sheet doesn't mention an optimum air temperature range when applying the primer. Is 30-40 deg. F too cold? Or should I wait for spring and 60 degree temps?

Steve,

I know that Dupont makes ?Variprime 620S - Fast Converter? for cold temperatures, and ?Variprime 614S - Slow Converter? for hot temperatures vice the standard 'Variprime 616S - Converter'. However, I don't know what specific numbers define cold and hot.

Variprime and outside air temps

Steve:

Living in NE Wisconsin I can chime in here with some experience. I have primed RV parts all winter long with no trouble. I set up a sawhorse outside in the driveway and hit the parts out there. Afterward I take the primed parts into the heated garage and they dry up just fine. Before I had the heated garage (AKA airplane assembly facility) I took the parts down into the basement. Made the basement smell for a day, but the wife didn't divorce me over it.

You will find that the flash time is extended in the cold, but it really isn't a problem.

Regards,
