Described is a cyanacrylate adhesive containing as plasticizer at least one partial and/or full ester of aliphatic mono- or polycarboxylic acids with 1 to 5 C-atoms bound directly to each other and aliphatic mono- to pentahydric alcohols with 1 to 5 C-atoms bound directly to each other, the number of C- atoms bound directly to each other in the other aliphatic groups being at the most three when one aliphatic group contains 4 or 5 C-atoms. Even at high plasticizer concentrations, the shelf life is good. This adhesive is a pressure sensitive adhesive. The addition of up to about 20 % of plasticizer causes hardly any increase in the setting time.
L'invention concerne un adhésif du type cyanoacrylate contenant comme plastifiant au moins un ester partiel et/ou complet d'acides aliphatiques monocarboxyliques ou polycarboxyliques comportant 1 à 5 atomes de C liés les uns aux autres directement, le nombre d'atomes de C liés les uns aux autres directement contenus dans les autres groupes aliphatiques étant de 3 maximum lorsqu'un groupe aliphatique contient 4 à 5 atomes de C. Même avec des concentrations élevées de plastifiant, la stabilité au stockage de cet adhésif est bonne. Cet adhésif adhère sous l'effet d'une pression. L'addition de jusqu'à environ 20 % de plastifiant n'entraîne pour ainsi dire aucune augmentation du temps de prise.
