The Universal Selection Source: Coatings Ingredients

Radiation Cured Coatings (UV/EB) Channel
Radiation curing technology is a current growing process to cure and dry coatings. Coatings are cured by ultraviolet or electron beam radiation. Radiation cured coatings present many advantages and are applicable to a wide range of substrates and particularly for heat-sensitive substrates (wood, plastic...). These coatings have replaced many conventional low solids, solvent-borne coatings and can be considered as eco-friendly technology without any VOC emissions and no flammability.
