Curing is a photochemical process in which a high-intensity electromagnetic wave is used to dry inks, coatings, or adhesives. Basically, this process involves mixing of liquid monomers and oligomers with a small portion of photo-initiators, which is then exposed to energy. The inks/coatings/adhesives then harden almost instantly. The traditional method involved conventional heat and drying methods, which relied on the principle of solvent evaporation and reduced the initial application of coatings by at least 50%, leading to generation of environmental pollutants and loss of product volume. However, the curing technology is beneficial as it use reduces waste, energy use, and pollutant emission and provides higher productivity. Currently, the two parallel competitive streams in energy curing technology are UV (Ultraviolet) and EB (Electron Beam). The curing technology is applicable across automotive, telecommunications, electronics, graphic arts, and glass & plastic decorating industries.
