Water-Based Coatings and Paints: This is a primary application. The medium wave IR spectrum is highly absorbed by water, making these heaters exceptionally efficient for drying water-based paints, adhesives, and coatings on substrates like wood, metal, and paper.
Printing and Textiles: They are widely used for drying inks on paper after printing and for drying dyes and finishes on textiles.
Powder Coating: In powder coating applications, medium wave heaters are used for the "gelling" or pre-curing stage, where the powder is melted into a smooth film before the final cure.
