Vernis en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : UV-curable water-borne coatings are attracting more attention due to th ecombined advantages of UV-curing systems and water-borne coatings, which include matting ease, handling efficiency, the fact they are monomer free, and offer a faster manufacturing throughput. However, good chemical resistance and physical drying can be a challenge. Two new approaches have turned this around, and offer good chemical resistance, hardness, and physical drying for clear and pigmented coatings.

Vernis -- Séchage sous rayonnement ultravioletIndex. décimale : 667.9 Revêtements et enduits Résumé : Ultra Violet curing technology may be new in many industrial and automotive industryies, but for more than three decades it has been used in other industries, because of low capital investment, low energy consumption, high solids, plastics and other heat sensitive substrates can be coated and cured. UV curing technology also plays a major rote in the consumer electronics industry. For instance, in the case of tell phones, UV technology is used in the coating of plastic housings, coatings to protect internal electronics, UV adhesive bonded components and even in the production of the colour screens found on some phones. Similarly, the optical fiber and DVD/CD industries use UV coatings and adhesives exclusively. Recent developments of new UV curable resins, which meet the high demands of automotive applications, in combination with a new lamp technology offer extremely fast drying of paints.
