In the present study, a film of silane (3-glycidoxypropyl trimethoxysilane) was
applied as pretreatment in nanocomposite coatings prepared with epoxy resin
DER 331 and montmorillonite modified with organic groups (MMT). The epoxy-
MMT coatings were prepared at different proportions of 0, 0.5, 1, 3 and 5%
weight of MMT. The coatings were applied on carbon steel substrates and cured
at 120 ° C for two hours, the carbon steel substrates were previously treated.
The coatings were characterized using physical techniques such as Scanning
Electron Microscopy, Fourier Transform Infrared Spectroscopy,
Thermogravimetric Analysis and X-Ray Diffraction. Electrochemical impedance
spectroscopy (EIS) was used to evaluate the anticorrosive performance of the
coatings. The results of the characterization of the coatings and the
electrochemical evaluation by EIS showed the formulation with the best
anticorrosive behavior in a 5% by weight NaCl solution.
