UV Curing Agent
UV curing agents—primarily photoinitiators and photosensitizers—generate reactive species such as free radicals or cations upon exposure to ultraviolet light, initiating rapid polymerization and crosslinking of UV-curable resins within seconds. These agents enable energy-efficient, solvent-free cure processes ideal for high-speed production lines in printing, electronics, and wood finishing. Selection of the appropriate UV curing agent depends on lamp spectrum, resin chemistry, and required cure depth.
