UV curing is a photopolymerization process in which UV energy is used to solidify liquids. UV LED curing systems are now the technology of choice across a wide range of applications including printing, 3D printing, coatings, and adhesives due to the inherent value of an LED solution. They offer vastly improved lifetimes, reduced maintenance costs, significant energy savings, and with no ozone emissions or mercury content, offer more benefits than traditional technologies. In addition, the “cold cure” offered by LED-based systems is ideal for heat-sensitive substrates or thin films.
