Ligna 2023: IST Metz presents UV, LED and excimer technology for wood applications

The BLK LAMPcure was developed for the highest industrial requirements and can also be supplied in the LED version LEDcure with 365, 385 or 395nm wavelength for a wide range of applications. Angeling by means of UV or LED technology influences the feel of the coating even after curing. Additional properties such as a soft-touch surface or an anti-fingerprint effect can be achieved in this way. At a wavelength of 172nm, excimer lamps have an enormously high-energy emission that starts a polymerization process in the uppermost part of a layer of UV-curable coating. The penetration depth of the UV emission is comparatively low, so this process leaves a thin film on the wet coating without affecting deeper layers of coating. Since this film formation is subject to shrinkage, the film near the surface exhibits microfolds, resulting in a matte surface. These can be cured in the final cure using conventional LAMPcure technology. The result is a mechanically and chemically highly resistant and deep matt surface.

Also on the Ligna stand in Hanover will be UK sister company IST Intech, which specializes in LED solutions for industrial applications. The air-cooled LEDcure VZ has been specifically designed to meet the needs of the wide-format printing industry and has an output of 16W/cm³. Thanks to XT8 LED booster technology, the LEDcure VZ scores with up to 30% more power than conventional LED systems. The higher curing speeds allow the LED systems to cover a wide range of customer applications. All products from Metz feature an identical control system.
