“…The data show that the addition of clay did not reduce the adhesion of the coating to the substrate. Similar results were obtained by Bagherzadeh & Mahdavi 18 and by Nematollahi et al 24 , who studied the addition from 1 to 5 wt% of montmorillonite clay in formulations of epoxy resin-based liquid coatings.…”

The high intercalation of the epoxy resin towards the interior of the OMMT galleries of the cured samples is more relevant for the EPC/2-30B sample, with a shift of the "d 001 " basal plane towards values higher than 5.25 nm (Table 1), which results in a nanocomposite with an exfoliated structure.…”

It is probably associated with the lower clay concentration and the high shear during the manufacturing process 18,21 . Transmission electron microscopy was used to characterize the dispersion of the filler particles in the polymer matrix and the morphological structure of the cured samples.…”

The aim of this study was to evaluate the use of iron-nickel oxide (Fe 2 O 3 .NiO) nanopowder (FeNi) as an anti-corrosion pigment for a different application. The corrosion protection ability and the mechanism involved was determined using aqueous solution of FeNi prepared in a corrosive solution containing 3.5 wt.% NaCl. Anti-corrosion abilities of aqueous solution were determined using electrochemical impedance spectroscopy (EIS) on line pipe steel (API 5L X-80). The protection mechanism involved the adsorption of metallic cations on the steel surface forming a protective film. Analysis of EIS spectra revealed that corrosion inhibition occurred at low concentration, whereas higher concentration of aqueous solution produced induction behavior.

ResumoNo presente trabalho a argila montmorilonita sódica (MMT-Na + ) foi funcionalizada com 3-aminopropiltrietóxisilano (γ-APS) e incorporada em uma formulação comercial de tinta em pó base epóxi na proporção de 8% em massa e aplicada em painéis de aço carbono 1008 por pulverização eletrostática. Foram realizados ensaios de aderência, flexibilidade, impacto e desempenho à corrosão em névoa salina. A presença da argila não afetou as propriedades mecânicas do filme, contudo uma maior migração subcutânea foi verificada após a realização do ensaio de névoa salina, o que pode comprometer a utilização das tintas obtidas como revestimento protetor.

MECHANICAL PROPERTIES AND CORROSION PROTECTION OF CARBON STEEL COATED WITH AN EPOXY BASED POWDER COATING CONTAINING MONTMORILONITE FUNCTIONALIZED WITH SILANE AbstractIn the present work the MMT-Na + clay was functionalized with 3-aminopropyltriethoxysilane (γ-APS) and incorporated in a commercial formulation epoxy-based powder coating in a proportion of 8 wt% and applied on 1008 carbon steel panels by electrostatic spray. Adhesion, flexibility, impact and corrosion performance in salt spray chamber tests were performed to evaluate the coatings. The presence of clay did not affect the mechanical properties of the film, however greater subcutaneous migration was assessed after the completion of salt spray testing, which can compromise the use of paints obtained as primers.
