摘要

The utilization of ultraviolet (UV) curing for a variety of coating applications has become a fact of life for a number of industries, being graphic arts (printing), wood (finishing), plastic, metal and electronics industries. However the use of UV-curable systems in metal coatings is still confined because of certain limitations like application viscosity, adherence and flexibility, or corrosion protection of the steel substrate. In this particular study high-throughput technologies have been applied for the development of novel UV-curable coatings on steel surface. The advantages of 100 percent (i.e. water and solvent-free) UV curable coating materials leads to: High savings of energy during the drying and hardening process which are favourable from both an economic and ecologic point of view, Low requirements in time and space which fit in with the integration into rapidly clocked production processes, Complete elimination of VOC offering advantages both for environmental and health reasons, and High chemical and mechanical resistance properties of the cured coatings because of their high cross-linking density.
