UV curing is a photochemical process in which high-intensity ultraviolet light is used to instantly cure or “dry” inks, coatings or adhesives. UV curable inks and coatings were first used as a better alternative to solvent-based products. The chemical reactions of UV curing rely on photoinitiators dispersed within specially formulated inks, coatings, adhesives, and extrusions.
The process of UV curing typically includes the following steps: applying the UV curable formulation to the substrate, exposing it to ultraviolet light, and allowing it to cure. The advantages of UV curing include its speed and ability to reduce flaws and errors by decreasing the time needed for drying or curing.
UV curing is a low-temperature, high-speed, solvent-less photochemical process that uses high-intensity electronic ultraviolet (UV) light to change inks, coatings or adhesives. UV curing technology is using light to cure a chemical substrate by irradiating ultraviolet rays (UV) into ultraviolet curing resin (UV curing resin).
