UV curing systems and their formulatory components such as photoinitiators, liquid phase monomers, oligomers, prepolymers, etc. have grown remarkably over recent years, especially in the graphic arts, inks, and coatings industries. Photogeneration of Reactive Species for UV Curing presents the state of the art in photocuring technology, and provides an in-depth review of recent developments and literature in the field. Topics discussed include the theory of photocuring, photoactive compounds for the generation of reactive species, polymerization, resin systems, industrial applications, risks and toxicity, and more.

From the Preface: “This is essentially a book about ultraviolet (UV) curing, although related electro-magnetic radiations are described. It is a general work not specifically aimed at presenting new information but rather drawing together all the important aspects of radiation curing...[T]he importance of photocuring has arisen from existing and impending legislation curtailing the employment of solvents, its tendency to develop coating end-properties immediately and its energy economics. These factors position it in the same league as other `clean' technologies. There are two prime differences between radiation curing systems and conventional thermal curing systems. These are the absence of solvents in the former and the polymerization mechanism of the formulation components...”

Target Audience: Both experienced and novice researchers and technologists concerned with radiation curing, as well as upper-level students of the field.
