Abstract
A method and arrangement for curing paint films and coating compositions by means of infrared radiation emitted by IRASERS, whereby the intensity of the IRASER beam is determined or controlled by the simultaneous measurement of the surface temperature of the coating being cured, and programs therefor, are described. Uniformity of cure of the paint films and coating compositions is obtained.
Claims10
System for curing protective coating compositions over a large area with infrared radiation emitted by IRASERS comprising
- --a composition to be cured;
- --an IRASER source;
- --fixed mirror means for receiving IRASER beams from said IRASER source;
- --movable mirror means movable around two axes so constructed, arranged, and positioned with respect to said fixed mirror means and said composition so as to simultaneously receive IRASER beams reflected from said fixed mirror means;
- direct received IRASER beams to said composition to be cured in a scanning pattern;
- simultaneously receive heat rays from said composition and direct said received heat rays to temperature-responsive means, and
- --temperature-responsive means for receiving and measuring the temperature of heat rays so constructed, arranged, and positioned with respect to said movable mirror means to receive said heat rays from said movable mirror means, said system providing uniform curing of said protective coating over a large area.
