CA 2439769

The invention relates to a mixture for the application of a polymeric coating to a substrate. Said mixture comprises water and optionally an organic solvent, at least one water-dispersible, radically-polymerisable compound, at least one water-dispersible, polymerisable cross-linking compound and at least one water-dispersible compound which forms free radicals as an effect of actinic radiation. The radically-polymerisable compound can not fully set with the free radicals formed on irradiation with actinic radiation at room temperature, but rather comprises further reactive bonds which lead to a further or complete setting on contact with the cross-linking compound. The invention further relates to a method for the application of a non-adhesive corrosion protection layer to a substrate, by application of a mixture to a surface of a metallic or polymeric substrate, drying the mixture and irradiation of the applied coating with actinic radiation of such an intensity and for such a period that a solid, hard, tough coating is formed.

La présente invention concerne un mélange pour l'application d'une couche polymère sur un substrat. Ce mélange contient de l'eau, éventuellement un solvant organique et au moins un composé dispersible dans l'eau radicalement polymérisable, au moins un composé dispersible dans l'eau, polymérisable et réticulable ainsi qu'au moins un composé dispersible dans l'eau formant des radicaux libres sous l'effet d'un rayonnement actinique. Selon cette invention, le composé radicalement polymérisable ne peut pas complètement durcir à température ambiante avec les radicaux libres formés sous l'effet du rayonnement actinique, mais présente des liaisons réactives qui, en contact avec le composé à post-réticulation, conduisent à un durcissement étendu ou complet. Cette invention concerne également un procédé d'application d'une couche anticorrosion glissante sur un substrat, lequel procédé consiste à appliquer un mélange sur la surface d'un substrat métallique ou polymère, à sécher ce mélange et à soumettre le revêtement appliqué à un rayonnement actinique d'une certaine intensité, jusqu'à ce qu'une couche solide, dure et tenace soit formée.
