Title: A METHOD OF COATING A SUBSTRATE
Abstract:
A method of coating a substrate comprises the steps of applying a coating composition to selected areas of the substrate. The coating composition comprises a mixture including at least a reactive part. The reactive part comprises between 30 % and 100 % multi-functional material, and is photoinitiator free. The coated substrate is exposed, in a curing zone, to ultra-violet light from at least one lamp which has a power output of at least 140 wats per linear centimetre. The ultra-violet light initiates curing of the coating. A substantially inert atmosphere is maintained in the curing zone where the substrate is exposed to the ultra-violet light.
