UV curing for metal substrates is a relatively newer development for the radiation cure market. Previous issues with adhesion problems have been solved and it is one of the fastest growth areas in the UV cure market. There are many advantages of UV over thermally cured coatings, with lower applied cost being the most significant due to lack of thermal cure ovens. The combination of the high heat capacity of metal and the high heat requirement of most thermally cured coatings results in significant costs involved in the processing of the finished parts. This is particularly important for larger metal parts, where it can take a very long time to get the part to the temperature required for cure. The cost savings seen when switching to UV cure can be very substantial in these situations.
UV cure coatings are also 100% solids with no VOC or HAPS, resulting in further cost savings by elimination of incinerators or oxidizers for removal of VOC. Current applications of UV cure coatings in the metal market include automotive refinish, automotive underhood parts, brake parts, wheels, tube & pipe, rigid packaging (food and aerosol cans), oil filters, propane tanks and others.
