Coil coating is a continuous process in which metal strips such as steel, aluminium or stainless steel are coated and then cured. IST METZ develops UV systems that are tailored to the requirements of continuous coil coating processes and the respective production environment.
Depending on the application, UV, LED-UV and excimer systems can be used for curing and surface finishing. A variety of UV-curable coating systems can be processed in this way.
Unlike thermal drying, UV curing is based on a photochemical reaction. This means that suitable coatings can be cured within a short time and processed immediately afterwards.
The short curing times enable compact system designs and can reduce the space required compared with conventional thermal drying processes. UV systems can also be integrated into new or existing coil coating and galvanising lines.
Depending on the coating and process configuration, the following options are available, amongst others:
UV systems from IST METZ can be used on a variety of metal substrates, such as stainless steel, steel, galvanised steel, aluminium and wires.
Typical applications include the curing of primers and topcoats, as well as coatings for corrosion protection, scratch resistance or anti-fingerprint surfaces. The surface properties that can actually be achieved depend on the coating system used and the respective process parameters.
Depending on the application, UV curing can also be carried out under inertised conditions using nitrogen.
Our UV systems for coil coating are tailored to the specific production line and the requirements of the curing process. Amongst other things, we use high-performance, water-cooled UV systems such as the BLK.
When designing the system, we take the following factors into account, amongst others:
To ensure safe and service-friendly operation, the systems can be fitted with additional protective and maintenance features tailored to the specific production environment.
IST METZ supports you from the design of the UV process right through to its integration into the production line:
