UV, also known as UV curing, is the use of medium and short wavelengths (300-800 nm) of UV light. Under UV radiation, photoinitiators in liquid UV materials are stimulated to become free radicals or cations, which triggers activity The process of polymerizing a functional polymer material (resin) into an infusible solid coating is a new, environmentally friendly, low-VOC technology emerging in the 1960s.
