Abstract: front page image
(EN)The subject of the invention is a conductive corrosion protection coating varnish composition that comprises an oligomer or polymer that is a precursor of polyurethane, a UV crosslinking agent, silver nanowires and an agent for dispersing said nanowires. The invention additionally relates to a process for protecting a substrate by depositing a film of a composition of the invention for which the film is polymerized by UV irradiation to form a thin protective layer on the substrate.
(FR)L'objet de l'invention est une composition de vernis de revêtement de protection anticorrosion conducteur qui comporte un oligomère ou polymère précurseur du polyuréthane, un agent de réticulation sous UV, des nanofils d'argent et un agent de mise en dispersion desdits nanofils. L'invention concerne en outre un procédé de protection d'un substrat par dépôt d'un film d'une composition de l'invention pour lequel le film est polymérisé par irradiation UV pour constituer une couche mince protectrice sur le substrat.
