BILAMINATE POLYMER COATED METAL STRIP AND METHOD FOR MANUFACTURE THEREOF |
摘要 |
A metal substrate having a first thermosetting elastomer layer and a second thermoplastic layer, both layers being chemically bonded to the substrate, and a method of manufacture therefor. Preferably, the first layer is extruded EPDM which is bonded to the substrate by with a heat-activable polyisocyanate adhesive and the second layer is extruded PVC which is bonded to the substrate by a heat-activable modified acrylic adhesive. Flock may be chemically bonded to a portion of the EPDM. An automotive trim product is disclosed. The preferred method of manufacture is a continuous process involving the steps of applying EPDM adhesive to the substrate; heat activating the adhesive; extruding the EPDM onto the substrate; applying PVC adhesive to the substrate; heating the partially coated substrate to concomitantly activate the PVC adhesive and cure the EPDM; and then extruding the PVC onto the substrate. |
