Through test we had determined an ideal method of disposition on the surface of MDF, adopting single factor experiments to design method for powder coating curing process test. The performance of the coating referenced to the national standards. The results of the experiment are as follows : ⑴ the process conditions for optimum coating performance and decorative effect is to use the 320P# sandpaper to frost the surface of MDF and then placed them in a constant temperature oven of 60℃ to drying about 30 min, and then put them under an infrared lamp to heating and curing, the temperature of the infrared lamp is about 155℃ and the curing time is about 5 min; ⑵ The finishes’ degree of cure under the optimal process conditions has meet the standard, the adhesion level is 0, the scratch resistance level is qualified, the smoke hot resistance level is 4, and the anti-pollution resistance level is basically qualified.
