Abstract:
(EN) The invention relates to a cyanate ester based adhesive comprising a component A which has at least one cyanate ester with at least two OCN groups, and a component B which comprises at least one catalyst for the trimerisation reaction of OCN groups to form a triazine ring. The catalyst is retained releasably on a carrier, particularly a pyrogenic silica.
(FR) L'invention concerne un adhésif à base d'ester de cyanate comprenant un composant A, qui renferme au moins un ester de cyanate comportant au moins deux groupes OCN, et un composant B, qui comprend au moins un catalyseur destiné à la réaction de trimérisation de groupes OCN pour former un cycle triazine. Selon l'invention, le catalyseur est retenu de manière réversible sur un support, en particulier une silice pyrogénée.
(DE) Die Erfindung betrifft einen Cyanatester-basierter Klebstoff um- fassend eine Komponente A, welche mindestens einen Cyanatester mit mindestens zwei OCN-Gruppen aufweist, undeine Komponente B, welche mindestens einen Katalysator für die Trimerisierungsreak- tion von OCN-Gruppen zu einem Triazinring aufweist. Dabei ist der Katalysator auf einem Träger, insbesondere einer pyrogenen Kieselsäure, reversibel zurückgehalten.
