The influence of the chloride concentration on the mass transport through unpigmented and plasticized chlorinated rubber films applied on steel was studied using the potentiostatic oxygen reduction as the test reaction. Besides, DC electrochemical measurement was also used in order to assess the coated steel deterioration with immersion time. From the experimental results it may be concluded that these varnishes applied in very thin films gave a good anticorrosive protection level, which was attributed to both, the coating permselectivity and its strong adhesion the steel substrate.
