Everyone wants their coatings to skin over, be dust-free, or dry faster. There are various technologies to accelerate the force curing of a coating such as; air movement, convection heat (oven) and infrared, besides accelerator additives from your coating supplier.

Additional clean compressed air movement across a wet coating will accelerate the time to skinover and cure. With the aid of a venturi design Dry-Off Guns can genereate a lot of air flow from a 8 cfm compressor.

Ovens (convection heat) can be batch or pass through in design, and can elevate the inside ambient temperature to over 500 degrees F. Ovens for plastic and wood substrates operate between 90-150 degrees F. While ovens for metal substrates operate between 150-500 degrees F. These ovens run on gas, electric, oil, propane, or steam and cure from the outside of the coating to the inside substrate.

I.R. Ovens (infrared) can also be batch or pass through in design. Unlike a convection oven the curing process is from the inside out. The specific infrared absorption wave length of organic coatings is most efficient between 3 to 10 microns. The entire substrate mass does not have to be raised to a specific curing temperature, which can reduce the curing time by 1/3. Curing from the inside out greatly reduces the chance of trapping water or solvents. One point we have to mention about I.R. curing, is it force cures only what the wavelength sees. So coated areas not in direct contact will not be forced cured, rather they will continue to air dry. These I.R. units or ovens run on gas, propane, or electric.

Dry-Off Gun, accelerates the drying of coatings, especially water-base coatings. Requires 7 cfm at 20-30psi and with venturi design generates 2 to 3 times more air. Allow coating to flash-off than at a distance of +30" apply the air. This gun has a fine inlet screen and adjustable air flow.
