Abstract

COMPOSIçãO DE ADESIVO EPOXI BICOMPONENTE, COMPOSIçãO DE ADESIVO EPóXI RESISTENTE à LAVAGEM, PROCESSO PARA UNIR SUPERFìCIES SEPARADAS, PEçAS, USO DA COMPOSIçãO DE ADESIVO EPóXI BICOMPONENTE E USO DE UM COMPOSTO DE AMINA. A presente invenção refere-se a uma composição de adesivo epóxi bicomponente compreendendo a) um primeiro componente compreendendo uma primeira resina epóxi e uma segunda resina epóxi, a segunda resina epóxi sendo flexibilizada por um elastómero, e b) um segundo componente compreendendo pelo menos um composto de amina com um ou mais grupos amino primários e/ou secundários, dito composto de amina tendo um peso molecular inferior a 450 g/mol. A relação do número total de grupos amino do composto de amina para o número total de grupos epóxi das resinas epóxi é de 0,01:1 para 0,5:1. A mistura dos dois componentes a) e b) resulta numa composição resistente à lavagem. Dita composição resistente à lavagem resulta, mediante cura térmica, num adesivo estrutural estável em colisão.
