Special Issue Information
Dear Colleagues,
The performance of organic coatings designed for appearance or functional purposes is generally assessed using accelerated test cabinets, where natural weathering is strongly exacerbated (this is carried out by closely controlling levels of ions, humidity, UV radiation, wet/dry time, etc.). These characterization procedures (which include UV weathering, thermal cycling, wet/dry cycling, and in many cases, a combination) aspire to simulate, as much as possible, the actual environment (though in an accelerated manner). The assessment of the extent of degradation after a number of hours of exposure (or a number of aging cycles) can be performed simply via a visual check or by using analytical tools, including electrochemical techniques (such as electrochemical impedance spectroscopy—EIS, electrochemical noise—ENM), spectroscopic techniques (such as energy dispersive X-ray spectroscopy—EDX, X-ray photoelectron spectroscopy—XPS, Fourier-transform infrared Raman—FT-IR, UV-visible absorption and fluorescence, and X-ray diffraction—XRD) and thermoanalytical methods (such as differential scanning calorimetry—DSC, thermogravimetric analysis—TGA, and thermomechanical analysis—TMA). The relevant amount of collected experimental data can be exploited to enable effective service life prediction models by comparing the effect of different natural environments to which identical coated coupons are exposed. Field tests and outdoor exposure are ideal for assessing the real durability of an organic coating. However, it takes a long time to gain useful information, particularly for industrial and marine coatings. For this reason, effective predictive models should be developed with durability of organic coatings based on short-term, reliable, accelerated tests. For this reason, a large amount of experimental data is required to implement, test, and validate these models. A comprehensive and systematic collection of experimental data regarding the degradation of organic coatings is essential, not only to unravel the corrosion and degradation mechanisms, but also to provide the basis for training AI-based models using a large set of labeled data.
This Special Issue will provide a snapshot of state-of-the-art advances and the very latest developments in the study of the degradation of organic coatings exposed to accelerated laboratory tests and/or natural environments.
You are invited to contribute to this Special Issue to share your experimental data and update this research field with state-of-the-art durability assessment methods.
The scope of this Special Issue will include, but is not limited to, the following fundamental and applied research topics:
- Corrosion and degradation of painted metals;
- Service life predictions models for organic coatings;
- New methods for the service life assessment and/or rating of organic coatings;
- Accelerated test methods for the assessment of the performance of organic coatings and painted metals;
- Outdoor aging of organic coatings;
- Electrochemical methods for outdoor corrosion monitoring;
- Effect of the weathering parameters on the aging of organic coatings.
