Certain organic coatings and linings can be used in such environments, either to protect vulnerable construction materials, or, in combination with fiber reinforcement, to replace them. However, degradation mechanisms of organic coatings in acid service are not thoroughly understood and relevant quantitative investigations are scarce. This review describes the uses and limitations of acid-resistant coatings in the chemical industry, with a comparison to alternative resistant materials based on metals or ceramics. In addition, coating degradation phenomena, caused by acid exposure, are mapped to the extent possible, and analysis methods for detecting coating degradation type and severity are listed and discussed. It is concluded that more knowledge on chemical and physical degradation mechanisms is required, and that improvements in resistance to elevated temperatures and abrasion would decrease the risk of use and increase the potential application areas of organic coatings exposed to acidic environments in the chemical industry.

Anticorrosive coatings / P. A. Sorensen in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 6, N° 2 (06/2009)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 6, N° 2 (06/2009) . - p. 135-176 Titre : Anticorrosive coatings : a review Type de document : texte imprimé Auteurs : P. A. Sorensen, Auteur ; Claus Erik Weinell, Auteur ; Kim Dam-Johansen, Auteur ; Søren Kiil, Auteur Année de publication : 2009 Article en page(s) : p. 135-176 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Anticorrosifs Anticorrosion Liants Pigments Index. décimale : 667.9 Revêtements et enduits Résumé : The main objective of this review is to describe some of the important topics related to the use of marine and protective coatings for anticorrosive purposes. In this context, "protective" refers to coatings for containers, offshore constructions, wind turbines, storage tanks, bridges, rail cars, and petrochemical plants while "marine" refers to coatings for ballast tanks, cargo holds and cargo tanks, decks, and engine rooms on ships. The review aims at providing a thorough picture of state-of-the-art in anticorrosive coatings systems. International and national legislation aiming at reducing the emission of volatile organic compounds (VOCs) have caused significant changes in the anticorrosive coating industry. The requirement for new VOC-compliant coating technologies means that coating manufacturers can no longer rely on the extensive track record of their time-served products to convince consumers of their suitability for use. An important aspect in the development of new VOC-compliant, high-performance anticorrosive coating systems is a thorough knowledge of the components in anticorrosive coatings, their interactions, their advantages and limitations, as well as a detailed knowledge on the failure modes of anticorrosive coatings. This review, which mainly deals with European experience and practice, includes a description of the different environments an anticorrosive coating system may encounter during service. In addition, examples of test methods and standards for determination of the performance and durability of anticorrosive coatings have been included. The different types of anticorrosive coatings are presented, and the most widely applied generic types of binders and pigments in anticorrosive coatings are listed and described. Furthermore, the protective mechanisms of barrier, sacrificial, and inhibitive coatings are outlined. In the past decades, several alternatives to organic solvent-borne coatings have reached the commercial market. This review also presents some of these technologies and discusses some of their advantages and limitations. Finally, some of the mechanisms leading to degradation and failure of organic coating systems are described, and the reported types of adhesion loss are discussed.

A char stratification approach to characterization and quantitative thermal insulation performance of hydrocarbon intumescent coatings / Ying Zeng in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 19, N° 4 (07/2022)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 19, N° 4 (07/2022) . - p. 1033-1043 Titre : A char stratification approach to characterization and quantitative thermal insulation performance of hydrocarbon intumescent coatings Type de document : texte imprimé Auteurs : Ying Zeng, Auteur ; Claus Erik Weinell, Auteur ; Kim Dam-Johansen, Auteur ; Louise Ring, Auteur ; Søren Kiil, Auteur Année de publication : 2022 Article en page(s) : p. 1033-1043 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Borate de zinc Caractérisation Carbonisation Hydrocarbures Intumescence (chimie) Métaux -- Revêtements protecteurs Polyphosphate d'ammonium Pyrolyse La pyrolyse est la décomposition ou thermolyse d'un composé organique par la chaleur pour obtenir d'autres produits (gaz et matière) qu'il ne contenait pas. L'opération est réalisée en l'absence d'oxygène ou en atmosphère pauvre en oxygène pour éviter l'oxydation et la combustion (L’opération ne produit donc pas de flamme). Il s'agit du premier stade de transformation thermique après la déshydratation. Elle permet généralement d'obtenir un solide carboné, une huile et un gaz. Elle débute à un niveau de température relativement bas (à partir de 200 °C) et se poursuit jusqu'à 1 000 °C environ. Selon la température, la proportion des trois composés résultants est différente.

Consequently, to improve formulations and understand the performance of such coatings, it is of great industrial and scientific interest to establish relationships between the char properties and the critical heating times of coated steel plates. In this work, a so-called Stratification Parameter (SP) that combines the relative expansions and insulation efficiencies of individual char layers (termed the sponge-like, the macroporous, and the compact phase, respectively), is introduced to characterize the properties of the multilayered intumescent coating char. An approximate linear relationship was revealed between the SP of the char and the fire-resistance performance (i.e., critical times to 400 and 550°C) of the intumescent coating. Furthermore, owing to the mapped-out exponential relationship between the dynamic viscosity minimum and the char appearance, it was discovered that the SP of the char can be effectively used to point out the required dynamic viscosity change of an intumescent coating to form a given char. Finally, results of thermogravimetric analyses suggest that constraining the coating mass loss during char degradation (to less than 28 wt% for the coatings of the present work) may prevent the formation of the less efficient sponge-like phase. The stratification methodology developed can be used to estimate expected thermal insulation properties of non-uniform hydrocarbon intumescent coating chars.

CoaST Maritime Test Centre : an investigation of biofouling propensity / Morten L. Pedersen in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 20, N° 3 (05/2023)

Langues : Américain (ame) Catégories : Encrassement Essais (technologie) Evaluation Revêtements -- Détérioration Salissures biologiques Test d'immersion Index. décimale : 667.9 Revêtements et enduits Résumé : The performance of fouling control coatings (FCC) is evaluated based on static exposure on test sites worldwide. There are different standards concerning the evaluation of the performance of the FCC. However, to the knowledge of the authors, there is not a standardized reporting guideline for how to evaluate the test site in which the FCC is exposed. Several factors such as water conditions, seasonal biofouling, and accessibility of sunlight can vary dependent on placement within or between test sites. This in turn makes it difficult to compare the performance of FCC exposed at different locations within a or at another test site. In this study, an analysis of the CoaST Maritime Test Centre (CMTC) has been performed to investigate how geographical orientation and changes in depth influence the biofouling propensity on coated panels. The investigation showed no statistical significance in the biofouling propensity between panels exposed to different geographical orientations at the CMTC. Similarly, no statistical significance was found between panels placed at different depths at the CMTC. If similar reporting was performed at other test sites, a better basis for comparison of FCC worldwide would be obtained, and this could be achieved with a standardized reporting guideline.

However, the long required lifetime of a barrier coating provides a challenge when attempting to evaluate coating performance. Diffusion cells can be used as a tool to estimate coating barrier properties and lifetime. In this work, a diffusion cell array was designed, constructed, and compared to previous designs, with simplicity being the most important design parameter. Sulfuric acid diffusion through five different coatings was monitored using a battery of cells, and a mathematical model was developed to simulate the experimental data and to study diffusion mechanisms. The diffusion cells allowed an objective and fast analysis of coating barrier properties. It was found that sulfuric acid deteriorated these properties as it diffused through the films. This was also expressed in the modeling results, where a three-step time dependency of the diffusion coefficient was required to simulate both acid breakthrough time and the subsequent steady-state flux. A vinyl ester-based coating proved to be the most effective barrier to sulfuric acid diffusion, followed by a polyurethane coating. Amine-cured novolac epoxies provided the least effective protection.
