UV curing is a photopolymerization process in which liquid monomers become hardened
polymers as a result of exposure to intense light from the ultraviolet portion of the electromagnetic spectrum. It is used
instead of heat to cure inks, coatings, and adhesives in a wide range of industrial applications including
medical devices, publishing, consumer products, plastics, telecommunications, metal and glass packaging,
and electronics. The process has a number of key benefits
- The UV process usually involves no solvents such as are used in conventional heat drying.
Therefore, there is neither loss of film
thickness nor any requirement for equipment to recover evaporated solvents.
- Excellent end product properties ... high scuff, abrasion, moisture, scratch and oil resistance.
- Minimal cleanup.
- Fast production speeds.
- Low energy requirements.
- Minimal floor space.
- Nearly instantaneous curing permits product handling and processing much sooner than with conventional heat drying.
- Superior bonding.
- Cooler processing
