Akzo Nobel Oppose Jotun’s Marine Coating Patent
This legal decision from the European Patent Office Boards of Appeal concerns a dispute over a patent for multilayer fouling release coatings used on marine structures. The case primarily examines whether the patent’s amended claims, held by Jotun A/S, satisfy requirements regarding added subject-matter and inventive step following an opposition by Akzo Nobel. The Board concluded that the specific combination of an anticorrosive epoxy primer and a layer containing silane-terminated polyurethane (SPU) was not explicitly obvious from the prior art. Evidence from experimental data demonstrated that this specific multilayer structure significantly improves interlayer adhesion compared to other chemical primers. Consequently, the Board set aside the original decision and ordered the patent to be maintained in amended form. This ruling clarifies that the technical advantage of enhanced bonding justifies the inventive nature of the coating system.

Preparation and Application of Benzotriazole-loaded CaSiO3 in Epoxy Coatings with Enhanced Corrosion Resistance
Traditional protective coatings often fall short in harsh environments, leading to costly repairs and downtime. This study introduces a groundbreaking solution: epoxy coatings enhanced with benzotriazole (BTA)-loaded calcium silicate (CaSiO3) nanoparticles. The research delves into the synthesis and characterization of these multifunctional particles, revealing their unique ability to release corrosion inhibitors in response to environmental triggers like pH changes. Unlike conventional coatings, which rely solely on passive barrier protection, this innovative system combines mechanical reinforcement with active, self-healing corrosion inhibition. The study meticulously examines the pH-dependent release kinetics of BTA, demonstrating how acidic or alkaline conditions at corrosion sites prompt the on-demand delivery of inhibitors. Mechanical tests confirm that the addition of CaSiO3, whether loaded with BTA or not, significantly improves the hardness and abrasion resistance of epoxy coatings without compromising adhesion. However, the true breakthrough lies in the electrochemical performance. After prolonged exposure to a 3.5% sodium chloride solution, coatings incorporating BTA-loaded CaSiO3 maintained remarkably high impedance values and capacitive behavior, outperforming both unmodified epoxy and epoxy with CaSiO3 alone. This superior performance is attributed to the localized release of BTA at the coating-metal interface, where it forms protective complexes that suppress electrochemical degradation. The findings underscore the potential of this smart coating system to extend the service life of metal structures in aggressive environments, offering a sustainable and cost-effective alternative to traditional corrosion protection methods.
Dual-stage Electrochemical Characterization of Waterborne Epoxy Coatings: from film formation kinetics under various environmental conditions to moisture resistance
Achieving reliable film formation in waterborne (WB) epoxy-amine coatings remains a critical challenge, particularly for anticorrosive applications where environmental conditions strongly affect performance. In this study, we apply electrochemical impedance spectroscopy (EIS) in a novel in situ configuration to monitor film formation continuously from the moment of application. Time-resolved impedance and capacitance measurements captured both physical drying and chemical curing, revealing their temporal decoupling and sensitivity to temperature and relative humidity (RH). Cross-sectional Scanning Electron Microscopy (SEM) confirmed that optimal curing conditions (20–40 °C, 20–40% RH) produced dense, homogeneous films with high final impedance and low water uptake, while extreme conditions (3 °C, 30 °C, 98% RH) yielded cracked, swollen, or skin-layered morphologies with compromised barrier properties. Post-formation humidity cycling and diffusion modeling further showed that well-formed films displayed low diffusion coefficients (≈2–4 × 10−14 m2/s) and near-Fickian transport, whereas defective films exhibited elevated diffusivity (>1 × 10−13 m2/s) and poor fits to Fick’s law. In-situ EIS as a powerful tool for characterizing WB coating formation demonstrated balanced drying and curing conditions are essential for achieving compact, ion-blocking networks. The methodology provides new insights into chemically curing WB coatings and offers practical guidance for optimizing application environments.
Free-radical-Mediated UV Aging Suppression and long-term Corrosion Protection Enabled by Hierarchical CeO2/U66@MXene-Modified Epoxy Coatings
In marine environments, UV-induced free-radical degradation contributes to the deterioration of organic anticorrosion coatings. Herein, a multifunctional epoxy composite coating with enhanced barrier integrity, UV aging durability, and corrosion protection is rationally designed. A hierarchical CeO2/U66@MXene nanofiller, consisting of lamellar 2D MXene nanosheets, octahedral UiO-66 metal–organic framework, and particulate CeO2 nanoparticles was synthesized via a stepwise solvothermal-hydrothermal strategy. Benefiting from its hybrid architecture and microporous framework, the resulting nanofiller exhibits strong UV absorption capability and markedly enhanced free-radical scavenging efficiency. Upon incorporation into the epoxy matrix, the resulting CUM/EP composite coating demonstrates improved structural integrity, mechanical stability, and corrosion resistance under accelerated aging conditions. After UV aging, the composite coating exhibits significantly improved retention of surface and interfacial properties compared to the neat epoxy. Specifically, the reduction in water contact angle decreased from 44.9% for EP to 5.7% for CUM/EP, while the loss in adhesion strength was mitigated from 76.5% to 26.1%. Furthermore, electrochemical impedance spectroscopy measurements revealed that, after 30 d of immersion in saline solution, |Z|0.01 Hz of CUM/EP remained as high as 2.45 × 109 Ω·cm2, exceeding that of the neat epoxy coating by more than two orders of magnitude. The outstanding durability is mainly attributed to the effects of the stable two-dimensional barrier provided by MXene, efficient UV attenuation, and the porous structure with a high specific surface area that exposes abundant active sites to promote radical reactions. These features enhance the radical scavenging activity of CeO2 and preserve the integrity of polymer chains during photoaging. Overall, this study demonstrates the feasibility of exploiting synergistic effects derived from hierarchical nanofiller architectures to simultaneously enhance UV resistance and corrosion protection, providing new insights into the design of durable protective coatings.
