At Ligna, which will take place from May 15-19 in Hannover, Germany, UV specialist IST METZ will present its comprehensive product portfolio of UV, LED and excimer technology for curing, gelling and matting coatings on wood and wood-based materials in Hall 17, Stand B77.
At a wavelength of 172nm, eximer lamps have an enormously high-energy emission that starts a polymerization process in the uppermost part of a layer of UV-curable curing. 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.
Also represented at the booth in Hannover is the British sister company IST INTECH, which specializes in LED solutions for industrial applications. The air-cooled LEDcure VZ has been specially developed to meet the requirements of the large format printing industry and has an output of 16W/cm³. Thanks to the 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 the METZ group of companies feature an identical control system.
