Abstract: Binder compositions based on vulcanizable rubber materials containing liquid polyenes, optionally solid rubbers and/or thermoplastic polymer powders as well as vulcanizing agents are suitable for the production of multilayer laminates consisting of two outer metal sheets and an intermediate binder layer. This intermediate layer may optionally contain in addition incorporated sheet material of synthetic fibers and/or metallic expanded meshes, wire meshes and the like.

Abstract: Hot-curing reactive compositions based on natural and/or synthetic elastomers which contain olefinic double bonds and vulcanization agents which contain, apart from conventional liquid polyenes, at least one liquid cis-1,4-polyisophere with a molecular weight between 20 000 and 70 000 and a vulcanization system consisting of sulfur, accelerators and quinonoximes, exhibit plastisol-like flow characteristics so that they can be applied at room temperature using conventional spray units. These compositions are suitable as joint-sealing and sealing compositions, as underseal adhesives and as structural adhesives such as e.g. lap-joint adhesives.
