UV LED curing refers to a technique that uses “energy” output from the light emitting diodes (LEDs) in the ultraviolet (UV) spectrum to treat coatings, adhesives, inks and other UV-curable materials.
One never gets a full 100% cure of these thermoset systems at relatively low temperatures because molecular mobility goes down dramatically as the adhesive increases in viscosity during curing.
Recent advances in materials and equipment are reportedly creating new demand for radiation-curable (radcure) coatings in a number of industrial applications.
