When coating surfaces, surface pretreatment plays a key role in determining the quality and durability of the coating. Thorough cleaning and degreasing are required for virtually all coating processes. Hot air is used to dry the residues left behind by liquid cleaners and solvents. In this way, the surfaces can be quickly and reliably prepared for the next step. Adhesives are used as part of laminating processes. These often have to be heated up before they are applied to improve the fluidity. Moreover, some adhesives have to be activated before they can be employed in a gluing process. Hot air is a great option in both cases. Hot air is even used for processes that take place downstream of the actual coating operation itself. Some coating systems have to cure through exposure to heat. Varnish is dried and cured with the help of hot air.

Leister has the solution
Leister air heaters and hot-air blowers can assist with the many different upstream and downstream processes that have to be performed in the context of coating. The wide power range means that you can select the optimum equipment for your process.
