A chemically resistant coating layer chemically bonded to a curable rubber layer is disclosed. The curable rubber layer material may be any silicone elastomer, organic elastomer, viton, sanoprene, or EPDM. The coating layer material may be polytetrafluoroethylene (PTFE) sheet or the like that will protect the curable rubber layer from solvents such as toluene, acetone, or other chemicals by reducing or preventing permeation of such solvents or chemicals through the coating layer material. Covers made from the chemically resistant coating layer chemically bonded to the curable rubber layer may be used for vial covers, septa and container covers for use as covers for containers that hold chemical samples for biotechnological, chemical or medicinal experiments or chemical analysis. In addition, the coating layer on a rubber layer may be an automotive windshield wiper blade or any laminated article having a coating layer on a curable rubber layer.
