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.
