A study of the photoinitiated cure of coatings

Abstract

This thesis describes an investigation into the photo- initiated cure of epoxide coatings. Diaryliodonium salt photoinitiators were prepared and characterised in the laboratory. The analysis and characterisation of some industrial epoxide resins was also carried out before they were used in the preparation of coatings. A series of lacquers was prepared and exposed to ultra-violet radiation. The cure characteristics of these coatings were investigated by qualitative and quantitative methods. This aspect of the work yielded some interesting results which are discussed in the final chapter.
