The invention relates to heat hardening reactive compositions based on natural and/or synthetic olefinically double compounds containing liquid elastomers and volcanic agents, which contain a conventional, liquid polyene with at least one liquid cis-1.4-polyisoprene with a molecular weight between 20 000 and 70 000 in addition to a volcanic system made of sulphur, atom smashers and quinonoximes, suitable for plastisol formed flow properties, so that they are applicable at room temperature with conventional injection arrangements. Said compositions are suitable as seam sealing and sealing material, as lining adhesives in addition to structure adhesives, for example, as raised seam adhesives.
L'invention concerne des compositions réactives thermodurcissantes à base d'élastomères et d'agents de vulcanisation liquides contenant des doubles liaisons oléfiniques naturelles et/ou synthétiques. Lesdites compositions contiennent, en plus de polyènes liquides habituels, au moins un cis-1,4-polyisoprène liquide ayant une masse moléculaire entre 20000 et 70000, ainsi qu'un système de vulcanisation composé de soufre, d'accélérateurs, et de chinonoximes. Lesdites compositions présentent un comportement d'écoulement de type plastisol de manière à pouvoir être appliquées à température ambiante au moyen de dispositifs de pulvérisation habituels. Lesdites compositions peuvent servir de masse de matage et de vitrification de soudures, d'adhésif de doublure inférieure, ainsi que d'adhésif structurel tel que par ex. un adhésif de joints à bords bridés.
