Ultraviolet curing (commonly known as UV curing) is a photochemical process in which high-intensity ultraviolet light is used to instantly cure or “dry” a coating. Using light instead of heat or air drying, the UV curing process is based on a photochemical reaction. Liquid monomers and oligomers are mixed with a small percent of photoinitiators, and then exposed to UV energy. In a few seconds, the coating products instantly harden.
UV curable coatings were first used as a better alternative to solvent-based products. Conventional heat- and air-drying works by solvent evaporation. This process shrinks the initial application of coatings depending on their solids content and creates environmental pollutants. In UV curing, there is no solvent to evaporate, no environmental pollutants, no loss of coating thickness, and no loss of volume. This results in higher productivity in less time, with a reduction in waste, energy use and pollutant emissions.
UV curing coatings offer many advantages over conventional coating technologies:
- Reduced or Near Zero voes / HAPs.
- Low Energy
- Instantaneous Cure - Fast, Compact Production Lines
- Little or No Added Heat
- Reusable / Efficient
- Performance Competitive
- Cost Competitive
- Able to be applied with a wide range of conventional application equipment.
- Environmentally Friendly
- Generally no Flammability Concerns
- Generally not Sensitive to Below Freezing Temps
