Abstract
A single use invertible elastomeric article with at least two polymeric layers. Each polymer in the two polymeric layers is a single, pure polymer and are different from each other, such that the single polymer of the first layer is not the same as the single polymer of the second layer. The first layer can comprise acrylonitrile butadiene and the second layer can comprise polychloroprene in an embodiment. The first layer is directly bonded to the second layer with a primer coating between the layers comprising a cationic polymer. There is a method of manufacturing the invertible elastomeric article comprising the steps of coating a former with a coagulant; applying a first polymeric coating of a single polymer; coating the first polymeric coating with a primer; and applying a second polymeric coating; the second polymeric coating comprises a single polymer different from the single polymer of the first polymeric coating.
