Abstract
a presente invenção refere-se a composições de resina epóxi termofixas que, por um lado à temperatura ambiente, em um estado incompletamente curado, apresentem uma alteração extremamente leve na forma e, por outro lado, desenvolvam uma aderência superficial elevada e, além disso, no estado totalmente curado tenham alta resistência a impacto e, ao mesmo tempo, apresentem alta aderência, particularmente, a substratos metálicos. estas composições são idealmente adequadas para a produção de elementos de reforço autoadesivos.
