Abstract[English]
An one component (1K) composition comprising: a) thermally-expandable thermoplastic microspheres; b) at least one epoxide compound; c) at least one compound which provides at least two amine hydrogens reactive toward epoxide groups; and, d) at least one accelerator, wherein the composition is characterized by a molar ratio of epoxide-reactive groups to epoxide groups from 0.6:1 to 1.2:1, preferably from 0.95: 1 to 1.1:1. The present disclosure envisages the use of this one component (1K) composition in providing an adhesive within a bonded structure upon curing of said composition under conditions in which the constituent microspheres retain their capacity to thermally expand.[French]
La divulgation concerne une composition à un composant (1K) comprenant : a) des microsphères thermoplastiques thermiquement expansibles ; b) au moins un composé époxyde ; c) au moins un composé qui fournit au moins deux hydrogènes d'amine réactifs vis-à-vis de groupes époxyde ; et, d) au moins un accélérateur, la composition étant caractérisée par un rapport molaire entre les groupes réactifs à l'époxyde et les groupes époxyde de 0,6 : 1 à 1,2 : 1, de préférence 0,95 : 1 à 1,1 : 1. La présente divulgation concerne l'utilisation de cette composition à un composant (1K) dans la fourniture d'un adhésif à l'intérieur d'une structure liée lors du durcissement de ladite composition dans des conditions dans lesquelles les microsphères constitutives conservent leur capacité à se dilater thermiquement.
