Here, we examine whether a similar system could be used for steel coil coating, without the requirement for expensive production-scale testing. Hansen solubility parameters (HSPs) were used to test the applicability of a typical, three-layer coil coating paint system for gradient self-stratification in wet-on-wet paint application techniques. As expected, the paint components are found to layer when placed on top of each other, remaining that way for some time. HSP analysis suggests, however, that the interlayer compatibility of some of the layers could be improved by solvent addition or substitution to produce a more graduated self-stratifying coating suitable for use in wet-on-wet techniques. Adhesion testing has subsequently indicated that cohesive failure occurs within the midcoat layer of the paint system, but adhesive failures are possible between the midcoat and topcoat layers. Using HSP-tailored paint systems in wet-on-wet paint application techniques, it may be possible to improve coating layer adhesion by “designing-in” gradient stratification during paint deposition.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"22 5","pages":"1819 - 1829"},"PeriodicalIF":2.8,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
