Reduced energy consumption compared to traditional UV lamps, less waste to be disposed of at the end of the lamp's life cycle and a complete absence of toxic elements like mercury. There are many advantages that make polymerisation with UV LED curing highly eco-sustainable as well as efficient.
Gloria Valtorta, Superfici's Business Unit Manager outlined the key advantages at Ligna.Stage, during an interview dedicated entirely to this technology.
When we talk about surface treatment, there are two main trends from the woodworking market: the request for an impeccable finishing quality and the need to optimise the processes to reduce consumption and waste. As Gloria Valtorta explained, Superfici has engineered a system of UV LED curing polymerisation that proves to be versatile on a wide range of products, suited to standalone machines as well as high-productivity machinery and lines.
This technological has several UV monochromatic sources of different wavelengths, in order to achieve a controlled multi-chromatic emission in a wider spectrum compared to the pure UV LED radiation. This allows you to achieve chemical-physical performances fully comparable with standard UV curing, while maintaining the typical advantages offered by led. The result is an exceptional finishing quality especially in the case of thermal-sensitive materials, because only a minimum amount of heat is released when drying. This ensures that the amount of waste falls dramatically and the finishing effect is unique.
