Durability of Acrylic Cataphoretic Coatings Additivated with Colloidal Silver

In this work, colloidal silver has been added into an acrylic clear cataphoretic bath, evaluating the effect of two different filler amounts on durability composite coatings. The three series samples were characterized by electron microscopy to assess possible change in morphology introduced silver-based additive. protective properties coatings evaluated a salt spray chamber exposure and electrochemical impedance spectroscopy measurements, evidencing negative provided high amount silver, which discontinuities matrix. Finally, was studied exposing them UV-B radiation, observing strong phenomenon degradation. Although coating containing concentrations demonstrated poor durability, study revealed that small can be used provide particular aesthetic features, but also improve performance
