Abstract

L'invention concerne un système d'étanchéité comprenant au moins un composant de base, comprenant au moins un polymère à terminaison thiol choisi dans le groupe constitué par les polysulfures, les polythioéthers, les polyéthers et leurs copolymères ; et au moins un composant durcisseur, comprenant au moins un polyépoxyde, le composant de base comprenant en outre au moins une base photolatente non ionique ayant la formule générale (PCG)-(BG)n, PCG signifiant "groupe photoclivable" ; BG signifiant "groupe de base" ; n étant 1 ou 2 ; la base formée après clivage de la liaison entre le PCG et le BG étant une base non ionique, et possèdant une valeur pKa de l'acide conjugué ≥ 10,0 ; et la base photolatente non ionique ayant une longueur d'onde de photoactivation destinée à cliver la liaison entre le PCG et le BG dans une plage de 300 nm à 420 nm.
