Title (EN) EPOXY THERMOSET MATERIALS AND THE USE THEREOF
(FR) MATÉRIAUX THERMODURCIS ÉPOXY ET UTILISATION ASSOCIÉE
Abstract:
(EN) Thermoset compositions are disclosed. Such thermosets are the reaction product of (a) an ambient temperature liquid epoxy-terminated prepolymer formed by reacting a polyoxyalkyleneamine having a molecular weight of from 3000 to 20,000 with an excess of epoxide, wherein the polyoxyalkyleneamine has at least 3 active hydrogen atoms, (b) a low viscosity second epoxy, (c) optionally a filler, and (d) a curing agent comprising at least one amine or polyamine having an equivalent weight of less than 200 and having 2 to 5 active hydrogen atoms. Such thermosets can be used in applications such as for sealants, adhesives, coatings, gaskets, jointing and castings.
(FR) L'invention concerne des compositions thermodurcies. Lesdites compositions thermodurcies sont le produit réactionnel (a) d'un prépolymère à terminaison époxy liquide à température ambiante formé par la réaction d'une polyoxyalkylèneamine ayant un poids moléculaire de 3000 à 20 000 avec un excès d'époxyde, la polyoxyalkylèneamine ayant au moins 3 atomes d'hydrogène actifs, (b) d'un époxy secondaire à faible viscosité, (c) optionnellement d'une charge, et (d) d'un agent de durcissement comprenant au moins une amine ou polyamine ayant un poids équivalent inférieur à 200 et ayant 2 à 5 atomes d'hydrogène actifs. Lesdites compositions thermodurcies peuvent être utilisées dans des applications telles que pour des matériaux d'étanchéité, des adhésifs, des revêtements, des joints d'étanchéité et des pièces d'assemblage et coulées.
