Alkyd based water-reducible anticorrosive paints and their antifungal potential

Abstract Concerns about ozone layer, contamination, fossils resources and health, has banned or restricted the use of traditionally organic solvents in paints. As a consequence, new resins that employed water as main solvent are being studied. Among these resins, alkyds most studied one they can also be synthesised from natural vegetable sources, making them more acceptable. The aim this paper was to study anticorrosive behaviour alkyd / polysaccharide paints containing zinc phosphate aluminum pigment their performance against fungal growth. Two different PVC (pigment volume concentration) were Painted panels by exposition salt spray humidity chambers, where rusting blistering degrees evaluated, electrochemical tests (corrosion potential measurements, ionic resistances determination, linear polarization curves determination). Results showed type used protect steel important protection. Besides, good selection both prevents fungi growth high humid environment.
