Direct measurement of coating temperatures in an automatic IR curing oven to determine the thermal cycle recorded a heating rate of 75°C per minute and a maximum temperature of 93°C under normal operating conditions. For the purpose of this test, four commercially available coatings, an acrylic polymer, a moisture-curable polyurethane, a fluroalkyl acrylate polymer, and a silicone polymer are chosen as representing the range of polymeric materials presently used in conformal coatings. All coatings are prepared by adding 30 percent of an appropriate solvent by weight, which includes toluene for the acrylic, silicone, and polyurethane polymeric materials, and 1,1,1-trichloroethane for the fluroalkyl acrylate material.
