Title (EN) METHOD FOR PREVENTING CORROSION OF METAL ARTICLES
(FR) PROCÉDÉ DE PRÉVENTION DE LA CORROSION D'ARTICLES MÉTALLIQUES
Abstract:
(EN) A method and for preventing the corrosion of metals and alloys and compositions for carrying out the method is herein disclosed. The method comprises applying to a metal or alloy a composition comprising two ionisable amorphous polymers having a low Tg. A first polymer comprises a non-ionisable polymer chain having two ends, wherein each end bears at least at least one ionisable acid group while a second polymer comprises a non- ionisable polymer chain having two ends, wherein each end bears at least at least one ionisable amino group.
(FR) L'invention concerne un procédé de prévention de la corrosion de métaux et d'alliages et des compositions pour la mise en oeuvre du procédé. Le procédé comprend l'application à un métal ou un alliage d'une composition comprenant deux polymères amorphes ionisables ayant une Tg faible. Un premier polymère comprend une chaîne polymère non ionisable ayant deux extrémités, chaque extrémité portant au moins un groupe acide ionisable tandis qu'un second polymère comprend une chaîne polymère non ionisable ayant deux extrémités, chaque extrémité portant au moins un groupe amino ionisable.
