Patent

CA 2472717

The invention relates to a coating mixture for applying a polymeric, corrosion- preventing protective layer to a metallic base for protecting an edge area, a soldered point, a weld seam and/or a repair point or for sealing the seam of one or more optionally interjoined strips, metal sheets and/or shaped parts. According to the invention, the coating mixture is largely or entirely free of water and/or of organic solvents, whereby it contains at least one radically polymerizable binding agent and at least one compound that forms free radicals when subjected to the action of actinic radiation. This radically polymerizable compound is largely or completely cured with the formed free radicals when subjected to actinic irradiation. The invention also relates to a coating mixture of the aforementioned type that additionally contains at least one post-crosslinking compound, whereby the radically polymerizable compound, when subjected to actinic irradiation, does not completely cure with the formed free radicals at temperatures ranging from 10 to 200 ~C but additionally has reactive bonds that lead to an extensive or complete curing when brought into contact with the post-crosslinking compound(s). The invention additionally relates to a method for producing a polymeric corrosion- preventing protective coating using this coating mixture. Finally, the invention relates to a protective coating produced in the aforementioned manner or to a metallic base correspondingly coated and to the uses thereof.

L'invention concerne un mélange de recouvrement utilisé pour appliquer un revêtement polymère anticorrosion sur un support métallique, afin de protéger la zone des arêtes, un point de brasage, une soudure et/ou un point de réfection ou afin d'étanchéifier la soudure d'une ou de plusieurs bandes, tôles et/ou pièces moulées éventuellement assemblées les unes aux autres. Le mélange de recouvrement est exempt, de préférence dans une large mesure ou en totalité, d'eau et/ou de solvant organique et contient au moins un liant à polymérisation radicalaire et au moins un composé formant des radicaux libres sous l'effet de rayonnement actinique. Le composé à polymérisation par voie radicalaire est durci dans une large mesure ou en totalité avec les radicaux libres formés, au cours du rayonnement actinique. L'invention concerne en outre un mélange de recouvrement de ce type, qui contient de plus au moins un composé à post-réticulation, le composé à polymérisation radicalaire ne durcissant pas entièrement, lors du rayonnement actinique, avec les radicaux libres formés, à des températures de l'ordre de 10 à 200 DEG C, mais présentant en outre des liaisons réactives qui induisent, au contact du(des) composé(s) à post-réticulation, un durcissement important ou total. L'invention concerne par ailleurs un procédé permettant de produire un revêtement polymère anticorrosion avec ledit mélange de recouvrement. L'invention concerne pour finir un revêtement ainsi produit et un support métallique recouvert en conséquence, ainsi que leurs utilisations.
