摘要：
The characteristics of siloxane-PMMA hybrid films permit the obtaining of coatings with thickness of few microns without cracking. Besides, the methacrylate groups (MMA) can be easily polymerizated by UV irradiation or thermal treatments. These hybrids can also be applied in anti-corrosive coatings for metals and alloys, replacing chromates which exhibit high toxicity. In this context, the aim of this work is to study the behavior of tinplate coated with a siloxane-PMMA hybrid film by dip-coating process and cured by thermal cure process. The systems were characterized by electrochemical, morphological and physicochemical analysis. Preliminary results showed that the systems studied presented a regular and adherent siloxane-PMMA hybrid film, which increased the corrosion resistance of tinplate substrates.
