OK than explain this, if my way is so dangerous. This was taken from a very well know powder site. here is the add.
INFRARED CURING
Completely Portable and Adjustable from 1' to 6' High Parts. Cures in half the time it takes the Electric Light Infrareds
This unit is Propane Driven and can be easily hook up at any place and any time for the most convenient way to cure your parts. Keep in mind because it is Propane Driven you will need a good ventilated area to run this Infrared Unit.
Contrary to most beliefs Powder can be cured with open flames. 95% of the industrial market uses Natural Gas or Propane to cure Powder Coated Parts. Powder cures by metal temperature only and not with just air temperature. That is the reason why parts have to be cured for 20-30 minutes in a conventional oven to allow for the heat to bring up the actual metal temperature for powder curing of 8-10 minutes at 375-400 degrees. As you can see below the pictures speak a thousand words because you can actually see the powder curing around the bicycle frame because the metal is heating and not the powder. We recommend curing parts with unit 6-10 inches away from part. Time will depend on metal thickness. We do express that a laser thermometer is the best way to judge the curing of the powder as it reads the exact metal temperature. We should have one available in approx. 1 week. With this unit you can virtually cure any size part from a bicycle frame to a car frame provided you can get to every angle for the heat to access. This unit by far exceeds our competitors product because of many reasons. One is that it is made of more durable components and heavier steel. The other is that it is completely mobile to allow you to move all around your parts for a better and faster cure. Because of the Propane we can reach a much higher and faster temperature than the 110 electric can ever achieve because of the limitations only a 110 plug can achieve in wattage output.
Other Reasons Are:
No Electricity Required. (Means it is completely Versatile)
Variable Controlled Heat for Small and Large Parts
Convenient (Portable and Easy to Light)
Fast (Gives You Heat When and Where You Want it)
Economical (Cost Pennies Per Hour to Operate)
Automatic Safety Shut-Off Valve Cuts Gas Flow if Heater Goes Out
No Unnecessary Heat, No Waste, Efficient (Just the Right Amount of Heat Where and When You Need It)
Durable Materials & Quality Construction
