Resumen

D'ALESSANDRO, Oriana; SELMI, Gonzalo; DEYA, Cecila  y  ROMAGNOLI, Roberto. Alkyd paints with mordenite exchanged with La (III) and Pr (III) as anticorrosive pigment for SAE1010 steel protection. Ingeniare. Rev. chil. ing. [online]. 2020, vol.28, n.3, pp.404-410. ISSN 0718-3305.  http://dx.doi.org/10.4067/S0718-33052020000300404.

The objective of this work was to formulate and prepare alkyd paints with new anticorrosive pigments based on exchanged mordenite, friendly with the environment. The electrochemical characterization of painted steel was done by: conductivity measurements, linear polarizations essays and corrosion potential measurements. The paint film tested in this case was removed and the steel surface analysed by scanning electron microscopy and energy dispersive X-ray analysis.

The results showed that the new pigments incorporated in the paint have acceptable anticorrosive properties, taking into account their low environmental impact and the use of a low-cost natural resource.

Palabras clave : Mordenite; lanthanum; praseodymium; alkyd paint.
