Infrared curing of resins, resin systems and other catalysed systems

In GB patent 2283 489, Delta Resins Ltd describes infrared curing of resins, resin systems and other catalysed systems. Infrared radiations are at the temperature corresponding to the peak frequency characteristic of the spectrum of the curing reaction of the particular system. Irradiation may take place in an oven with electrical elements controllable to attain temperatures the to nearest 0.1 °C, or in catalytic gas burners to thus provide infrared radiation of the optimum frequency. An example of curing all epoxy resin systems is given. Curing times of about ten minutes are achieved.
