This is a very readable review on the exciting, advancing technology of radiation curing. The principles upon which the technology is based, the equipment that is used and the materials which make up a radiation curable formulation are described. The applications of radiation curing are set to expand. Currently, the technology is used in coatings, graphic arts, printing inks, packaging, adhesives, optical and optoelectronic applications, composite production, rapid prototyping, electronics, with liquid crystals, in nanotechnology, for controlled-permeability membranes and hydrogels (including contact lenses), and for the vulcanisation of natural and synthetic rubber. These are all discussed in this review, with principle material types outlined. The review is well referenced to facilitate further reading. It is accompanied by around 400 abstracts compiled from the Polymer Library, most of which are cited in the text.

There are many possibilities for future developments in radiation curing. The technology permits extensive control over crosslinking, including reversal of the process of adhesion in some cases. This allows the production of release coatings and provides an easy method of removing expensive components at the end-of-life stage. It is also developing a role in medical applications. The prospects for functional and aesthetic coating applications are abundant with pearlescent coatings, liquid crystals in coatings and high gloss coatings, to name but a few. Radiation curing is generally environmentally friendly - dry powder coatings can eliminate the need for solvent-based products, and reversible adhesives can facilitate recycling. Thus legislation is fuelling the drive towards this technology.
