Abstract

L'invention concerne une composition et un procédé d'étanchéification et d'isolation de surfaces entre des pièces s'adaptant mutuellement. Le procédé peut être appliqué pour isoler et étanchéifier des plaques de piles à combustible, et consiste à appliquer un précurseur de revêtement sur au moins une surface de ladite plaque, et à durcir le précurseur de revêtement par exposition à un rayonnement. Les précurseurs de revêtement décrits comprennent ceux qui renferment un oligomère acrylé et un photo-initiateur capables de se polymériser sous l'effet d'un rayonnement ultraviolet ou d'un faisceau d'électrons. Les procédés et les précurseurs selon l'invention procurent certains avantages par rapport aux procédés et aux systèmes conventionnels pour l'isolation et l'étanchéification des plaques de piles à combustible, du fait que les précurseurs selon l'invention peuvent être appliqués rapidement et avec précision sur lesdites plaques, par exemple, par impression par masquage.
