This project aims to find solutions to some problems of aesthetic durability of the organic coated steel sheets that are receiving a growing interest in very important markets, like the household appliances and automotive ones. The objectives concern the understanding of: the processes of surface alterations (fingerprint, mar-scratch); the properties of clear coatings, to be applied on continuous lines, to preserve appearance during time. Three partners (Arcelor, DOC, CSM) have focused their attention on coatings for stainless steel (mainly for domestic appliances). The fourth partner (VASL) has studied coats for prepainted carbon steel (mainly for the automobile industries). Different technological tests and physical properties related to mar-scratch resistance have been studied. A test method, based on a synthetic mixture, has been set up to simulate and evaluate aesthetic alterations due to fingerprints. Many new coatings were characterised and special attention paid to UV-curable varnishes for the high performance expected in mar-scratch resistance, and to the possibility of substituting solvent-based treatments. From the assessment of new coatings, it results that almost all of them are able to reduce the fingerprint visibility, and in many cases mar-scratch resistance is improved. At the present stage, further important properties (general appearance, formability, etc.) still need improvements to fulfil the severe demands of markets such as automotive and household. However, among different systems, two coatings, both UV-curable, have been selected as they represent a good compromise among properties and have been tested on pilot lines.
