Abstract
Abstract An adhesion assistant or binder composition contains (a) 10 to 30 parts by weight of chlorosulfonated polyethylene, (b) 5 to 25 parts by weight of a di-C-nitroso aromatic compound, especially dinitrosobenzene, (c) 20 to 40 parts by weight of an organic polyisocyanate, (d) 10 to 30 parts by weight of chlorinated rubber, (e) 5 to 20 parts by weight of a phenol resin of the resol type having reactive groups and/or a compound containing more than one epoxide group in the molecule; as well as a process for producing composite bodies by vulcanization utilizes this adhesion assistant.
