Corrosion performance of paints in accelerated tests

Corrosion of metallic materials, especially carbon steel, is a major problem, since it occurs frequently in the most varied activities, such as in the chemical, oil, civil construction, automotive industries, among others. The most common way to combat corrosion is to paint the part, using paints that are basically composed of resin, solvents and additives, forming a protective layer on the metal surface. This project aims to develop low-cost chambers for accelerated testing and to study the corrosion protection offered by anticorrosive paints available on the market, applying them to combat corrosion in metallic material. The results show that it was possible to develop chambers for low-cost accelerated tests, using low-cost materials available in the local market, it was also observed that the corrosion protection offered by anticorrosive paints did not show efficiency in combating corrosion when exposed in the corrosive media of the accelerated tests.
