Coil coating

UV technology for processing coils

The IST Metz Group supplies specially developed UV drying systems for processing aluminium coils, metal coils, stainless steel coils or wires. The customers use the UV coating mainly to achieve corrosion protection, scratch resistance or anti-fingerprint properties, as well as to cure primers. Compared with using drying ovens for water-based coatings, UV drying offers extremely short drying and processing times, as well as significantly lower energy consumption. The UV systems from IST are specially tailored for use in coil coating. For example, strong steel wires are fitted in front of the UV lamps to protect the lamps from being damaged if the aluminium strip should break. Equally, the UV driers can be separated to guarantee very good access for maintenance and servicing, or if a coil breaks.
