Title (EN) POWDERABLE REACTIVE RESIN COMPOSITIONS
(FR) COMPOSITIONS DE RESINE REACTIVE POUVANT ETRE REDUITES EN POUDRE
Abstract:
(EN) A reactive resin composition, which is a fusible, solid optionally foamable, heat curable, epoxy functional reaction product with a Kofler Heat Bank melting point of not less than 55 °C, formed by mixing together: (A) epoxy resins of epoxy group containing compounds; (B) an amine solidifying system present in insufficient quantities to cause gelation after all the amino hydrogen atoms are consumed by epoxy groups, under the reaction conditions chosen for (A) and (B), and which yields a product with a Kofler Heat Bank melting point of greater than 55 °C and less than 120 °C and melting point stability of at least six months normal workshop temperatures; (C) a hardener system for (A) and the reaction product of (A) and (B) which is different from (B) and remains substantially unreacted under the conditions of reaction chosen for (A) and (B) with (A) and (B) and which is of low reactivity at normal workshop temperatures in the final solid epoxy formulation; optionally, (D) an expanding agent which is of low reactivity under the conditions of reaction chosen for (A) and (B) and which is of low reactivity at normal workshop temperatures in the final solid epoxy formulation; and optionally, (E) other additives that may be required to modify the physical properties of the cured or uncured composition.
(FR) Cette invention concerne une composition de résine réactive qui est un produit de réaction à fonctionnalité époxy, polymérisable à chaud, fusible, solide et éventuellement moussant, présentant un point de fusion Kofler Heat Bank d'au moins à 55 °C qu'on obtient en mélangeant ensemble: (A) des résines époxy ou des composés contenant des groupes époxy; (B) un système solidifiant les amines présentes dans des quantités insuffisantes pour induire la gélification après que tous les atomes d'hydrogène amino aient été épuisés par les groupes époxy, dans des conditions de réaction choisies pour (A) et (B), ce système donnant naissance à un produit se caractérisant par un point de fusion mesuré suivant la norme Kofler Heat Bank supérieur à 55 °C et inférieur à 120 °C et une stabilité du point de fusion d'au moins six mois dans des conditions de travail normales; (C) un système durcisseur pour (A) et pour le produit de réaction de (A) et (B) qui est différent de (B) et ne réagit sensiblement pas avec (A) et (B) lorsqu'il est soumis aux conditions de réaction choisies pour (A) et (B); ce système durcisseur présentant une faible réactivité à des températures d'atelier normales dans la formulation époxy solide finale; éventuellement (D) un agent gonflant qui présente une faible réactivité dans les conditions de réaction choisies pour (A) et (B) et qui présente une faible réactivité à des températures d'atelier normales dans la formulation époxy solide finale; et éventuellement (E) d'autres additifs qui peuvent être nécessaires pour modifier les propriétés physiques de la composition durcie ou non durcie.
