An Evaluation of different photopolymerizable systems with particular reference to their water dispersions

The UV curing coating process has aroused admiration and interest in technologists since it came on the scene of coating industry — just a long time ago — because of both the novelty of the idea and the easiness of the application schedule. Quickness and low energy demand are further peculiar characteristics of this technology, which was utilized in a first time for furnishings by using unsaturated polyesters and which later gradually expanded into other fields, like electronic industry, printing inks, optical fibres, etc. Simultaneously with the expansion of the UV curing coating market, a development has been taking place in the research of new, more sensitive and
specific photo—initiators and of more powerful and effective radiation sources, and progress in industrial implementation has been achieved.
