Infrared Emitters for Coatings

Many coating processes require heat: water and water-based lacquers are dried, powder coating is gelled and cured. Infrared heat can be precisely adjusted to the kind of coating. For example, medium-wave infrared heat is especially well absorbed by water. Therefore, infrared dryers can be used specifically to dry water-based coatings. This saves costs and improves quality. In other kinds of coating processes, IR heat penetrates the coat and heats the base material to ensure even drying. Nano-coatings are reliably heated by infrared emitters to the necessary high temperatures. Thus, compared to conventional methods such as hot-air drying, Heraeus infrared emitters can in many cases substantially accelerate the drying process.
