Abstract
The invention relates to a method of applying a powder coating to a substrate ( ), in particular a temperature-sensitive substrate such as wood, wood-fiber material, plastic, rubber, cloth, paper or cardboard, wherein a thermoreactive powder is applied as a base layer ( ) to the uncoated surface of the substrate ( ), and wherein by means of infrared radiation with at least some components in the near and/or short-wave infrared region the powder is warmed throughout to the cross-linking temperature and cured, or is warmed throughout to the gelling temperature and in a subsequent processing step cross-linking is completed and the coating is cured. To generate the infrared radiation in particular halogen bulbs ( ) are used in combination with a reflector ( ) to reflect the emitted radiation towards the substrate. The halogen bulbs ( ) are operated in such a way that the emitted radiation has a flux-density maximum in the near infrared.
