This paper presents the results of an in-depth investigation of the reactivity of photocurable systems consisting of acrylated monomomers/oligomers and photoinitiators by using Photo Differential Scanning Calorimetry (Photo-DSC) . Thus, photoreactivity can be expressed accurately as a function of photoinitiator structure. The results of these Photo

A brief summary of both free radical and cationic radiation curing chemistry is provided. Historical reasons for the rapid growth of this technology are reviewed, and a number of recent and emerging applications are discussed. It is shown that the technical and economic forces which have driven the rapid growth of radiation curing still exist, and

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 i

Various types of electron accelerators have been developed for coating purposes. Although they have many common characteristics, there are significant differences of technical origin, especially in the performance range limits. The actual performance requirements are determined by the application. We will report on our experience with three differe

Industrial applications of photo-induced chain crosslinking polymerisation processes have been increasing in recent years. Known examples, besides the classical use in coatings, are the replication of optical discs, of aspherical lenses for laser read—out systems, the in-line coating of optical fibres, the production of lenses and organic glass art
