UV curing principle

The curing process of UV varnish is that under ultraviolet irradiation, the photoinitiator produces free radicals or cations, thereby initiating the cross-linking reaction of monomers and oligomers. UV curing has the following characteristics:

Instant curing: Through ultraviolet irradiation, the varnish can be quickly dried in a short time, reducing the production cycle and improving efficiency.

Energy saving and environmental protection: Unlike traditional heating and drying methods, UV curing does not require high-temperature treatment, reducing energy consumption and carbon emissions.

Solvent-free formula: UV varnish usually does not contain solvents, avoiding the pollution of solvent volatilization to the environment.
