Abstract
The protection against corrosion in the automotive industry is a high impact problem on the economic view. Besides of an antirust characteristics, the coatings used in the automotive industries needs do have a good appearance and technical resistance. The multilayer coatings are normally compound per e-coat, primer, base and clear coat, where the primer can also be used as an e-coat substitute in rework processes. In the other side, the conductive polymers has been widely discussed as a coating material and the polyaniline-zinc composite had presented good results as an efficient material concerning the corrosion protection. Considering the automotive industry necessities and the polyaniline-zinc results, this study had apply the polyaniline-zinc composite in a multilayer coating used in the automotive industry, substituting the commercial primer in a common rework process. In addition, the results were compared with the commercial primer used currently. Then, the painted sets were evaluated regarding the visual aspects, corrosion and technical resistance and the results presented the polyaniline-zinc performance when applied together with other technologies as base and clear coats.
