Coating curing – the role of infrared

This article describes the background to the widespread application of infrared radiation as a curing technique for paints and coatings, from its origins in the 1930s to the present day. It explains the mechanism of infrared and elaborates on some of the developments which have been made in the technology, especially in terms of control and response. The benefits of infra‐red drying and curing are further illustrated by reference to case studies demonstrating infrared in action.
