Molded body of vulcanized rubber having firmly adhering varnish layer produced by applying a coating of varnish which has a compound with a member which will on subsequent vulcanization participate in the vulcanization reaction, to the surface of the unvulcanized molded body. Subsequently vulcanizing the coated molded body to cause the member to participate in the vulcanization and produce a vulcanized rubber molded body with a firmly adhering varnish layer.

Molded bodies of vulcanized rubber having a vulcanized-on layer of

Production of rubber articles by intensively mixing powdered caoutchouc and additives without vulcanizing accelerators to produce a homogenized caoutchouc mixture. The mixture is formed into semi-finished products which are irradiated with high-speed electrons to produce the rubber articles.

Method for producing rubber articles by subjecting powdered caoutchou

A release agent applied to the surface of a mold in the form of a film to permit ready removal of plastic, particularly polyurethane, from the mold. The release agent contains a film-forming substance having an affinity to the plastic and becomes attached to the plastic and is removed with the plastic when taken out of the mold thereby preventing buildup of film-forming substance in the mold. A cross-linking agent and/or a cross-linking catalyst and/or emulsifier and/or tenside may advantageously be incorporated in the release agent.
