Abstract
A method of providing a protective barrier between a plastic casing and a rubber layer molded over the plastic casing. The protective barrier is applied to the plastic casing and then the rubber layer molded onto the plastic casing over the protective barrier. The protective barrier prevents the rubber layer from reacting with the underlying plastic casing. In one embodiment, the plastic casing comprises a polycarbonate resin and the protective barrier comprises a polyurethane coating.
