ABSTRACT:
A composite comprises a coating which is adhered to a highly saturated elastomer having a corona discharge activated surface which is chemically fixed by a halogenating agent. A coating such as a paint, a weather-resistant film, etc., or an adhesive layer, is adhered to the activated and fixed surface. Various halogenating agents include N-halohydantoins, N-haloimides, N-haloamides, aqueous chlorine or bromine solutions, and acidified hypochlorite solutions. The composite is useful for EPDM roofing and consumer goods, e.g., a flexible polyurethane paint applied to the sidewalls of tires, as a decorated article, bonded composites, and the like.
