Infrared Heat for Functional Coatings
Water drips off shower walls, roof tiles repel dirt, facades stay glossy, frequently, all this is the work of coatings with functional properties. For building facades or roofs a dirt-repellant coating is very practical, in healthcare it helps to keep rooms cleaner and perfectly hygienic. With ships and aircraft, the repellent effect can save energy and can even be of vital importance. Algae or shellfish which cling to ships, significantly affect propulsion and ice crystals on aircraft are a safety risk.
Coatings with functional properties, many of which are nano coatings, are also used on machine and engine parts such as linkage shafts of ships’ propulsion systems, which are exposed to salt water or other unfavorable weather influences.
However, all protective coatings must be applied and dried very homogenously so that their functional property is effective evenly and reliably over the complete component.
This means that the coating must be sprayed on in very thin layers, which are then dried quickly without destroying the special properties of the coating. Infrared emitters transfer heat efficiently without contact, with the aid of electromagnetic waves, which generate the heat primarily in the material. As a result, the adhesion of disruptive particles in the sensitive coating during drying is minimized.
Infrared emitters offer very fast reaction times. Shortwave and Carbon emitters from Heraeus react within one to three seconds. This ensures that heating is controllable and, combined with temperature control, helps to eliminate overheating of materials.
Rapid change-over of different types of coating having different burn-in temperatures are possible. And it also saves energy when the heat source needs to be switched on only when it is needed.
