    摘要: The treatment of an uncured or partially cured rubber surface with a solvent mixture of a blend of n-heptane and iso-heptane. The treatment is to remove surface bloom and/or freshen the surface and to maintain or increase building tack. Cured adhesion can also be enhanced or maintained. An appropriate solvent mixture is provided. An article can be produced thereby as a cured assembly of rubber components. In one aspect, a purpose is to provide a suitable solvent mixture treatment of an uncured or partially cured rubber surface with a solvent mixture which has an acceptably minimal aromatic content, suitable drying time on the rubber surface and an acceptable odor in the workplace.

    摘要: There is disclosed a method for enhancing the cure of a sulfur vulcanizable elastomer which comprises adding to the vulcanizable elastomer a mixture of tall oil fatty acids comprising at least (a) from about 28% to about 55% by weight of oleic acid, (b) from about 25% to about 40% by weight of linoleic acid, (c) from about 4% to about 20% conjugated linoleic acid and (d) from about 0% to about 8% rosin acids. Use of a mixture of tall oil acids as a cure activator significantly lowers the cost of producing the vulcanizate while concomitantly improving the adhesion and dynamic properties of the elastomer.
