This study focused on analyzing the influence of three types of organic coatings on the corrosion rate of A-36 carbon steel. For this purpose, the coated samples were exposed to a salt spray chamber, simulating an aggressive environment, and their anticorrosion behavior was evaluated. Additionally, the impact of cleaning prior to the application of the coatings was investigated. The testing process was based on ASTM B117, which establishes the necessary parameters for accelerated corrosion testing in salt spray chambers, including the laboratory controls required to validate the results.The corrosion rate was calculated following the ASTM G1 standard, allowing comparison of the effectiveness of each coating in protecting the steel. Additionally, a visual inspection of the coatings was performed according to ASTM D610 to determine their corrosion rate.
