As paint cratering is a surface phenomenon, the causing chemicals can be minimal both in size and quantity, or more precisely, below the detection limit of many analytical techniques. In order to identify the chemical responsible for paint craters, a technique that is extremely surface sensitive, chemically selective and capable of imaging is required. Time-of-flight secondary ion mass spectrometry (ToF-SIMS) perfectly fits all these analysis requirements, and for the past decade we have used ToF-SIMS to identify automotive paint cratering chemicals. This article categorizes the paint cratering chemicals for the past decade and their distributions in terms of the four seasons. The information presented is expected to benefit both painting engineers and defect analysts in understanding possible/potential chemicals causing automotive paint craters, which is a costly failure in car manufacturing.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"22 1","pages":"447 - 459"},"PeriodicalIF":2.3,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142912993","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}

This design aims at providing corrosion protection via the controlled release of gluconate from LDH near the substrate, while at the same time contributing to the improvement of the polyurethane layer coating adhesion. The CaAl-LDH thin film was initially grown directly on AISI 1080/1010 carbon steel and modified with environmentally friendly gluconate molecules through an ion-exchange reaction. The effect of polyurethane treatments on the LDHs thin film was systematically explored: gluconate is either intercalated in LDHs or dispersed in polyurethane coatings, and the two systems are studied to understand the role of inhibitors in bilayer coating systems at defined conditions. The structural characteristics of the developed coatings were evaluated by scanning electrochemical microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (ATR-FTIR), and glow discharge optical microscopy (GDOES). The findings of electrochemical impedance spectroscopy (EIS) measurements on coated carbon steel substrates in NaCl solution demonstrated the significance of the bilayer film design for long-term corrosion protection, by combining active corrosion protection provided by the LDH conversion film with the passive barrier effect against electrolyte species rendered by the organic polyurethane layer. Additionally, improving the polyurethane coating’s wet adhesion to the substrate when applied onto CaAl-LDH opens new directions toward the co-development of surface treatments with organic coatings.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"22 2","pages":"619 - 630"},"PeriodicalIF":2.3,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622001","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}

OPTCM is used as a reflective coating that reflects the sunlight, reducing the electricity load on cooling system. The OPTCM easily gets degraded under sunlight and thereby limits its usage in building coating applications. To reduce the photodegradation of OPTCM, it is generally encapsulated with an inorganic metal oxide such as titanium dioxide, zinc oxide, etc. Different methods are discussed and illustrated further to achieve the necessary microencapsulation.
