The durability of a paint system is closely linked to a number of external factors, such as the marine environment in which it operates, the design of the hull and structure of the yacht, the surface preparation prior to coating application, and the application and drying methods used. In addition, the chemical and physical properties of the paint system, such as the type of binder and dry film thickness, are essential to its resistance to marine corrosion and other elements of the maritime environment.
To assess the impact of these characteristics, accelerated ageing tests are conducted. These tests, which include salt water, humidity and salt spray resistance assessments, are crucial in determining the ability of a paint system to resist marine corrosion and maintain its adhesion and protective properties against the demands of the environment.
It is very important to note that while accelerated weathering test results are valuable, they should be interpreted with caution by experienced personnel and not simply rely on a report with a pass or fail in accordance with an international standard.
Therefore, it is strongly recommended that paint manufacturers have a laboratory that has experience and knowledge in the field and can assist in the proper interpretation of the results.
This combination of testing and knowledge provides the objectivity and confidence needed to ensure the quality and effectiveness of corrosion protection application products. These tests are an essential tool for making informed decisions and continuously improving the strength and durability of coating systems.
