| Résumé : |
The author sees UV curing as the answer to 21st century demands.
The graphics arts, printing and wood coating industries have already been successful in making the transition from classic solvent-based inks and coatings to UV curing, systems, where the change in state from liquid to solid is almost instantaneous as the UV curable material is passed at high speed through a drying system.
As we move further into the 21st century, there is an ever-increasing demand for higher productivity and improved quality at reduced cost. Environmental concers also require that alternative processes be considered that use low odour, low toxicity chemistries that give no solvent emission and can be processed at high speed using more efficient lower energy systems.
Both decorative and functional UV coatings are available which can give enhanced performance over that of conventional chemistries. In addition to surface protection, their use can also extend to silicone release coatings, pressure sensitive & structural adhesives and gasketing elastomers.
New materials, such as UV powder coatings, are increase constantly emerging which can increase the scope over conventional finishing methods. |

- FIGURES : 1. New lamp designs, such as Aquacure, can be used on heat sensitive substrates. Cooling water is circulated through IR filters and cooled with a heat exchanger - 2. In a further development of Aquacure, the Monocure system (below) contains a single large diameter IR filter to create a compact unit - 3. Encapsulation or conformal UV coatings can be used in the electronics industry in a clean-room environments |
