Filed:

Jan 12, 1990

Appl. No.:

7/464073

Inventors:

Mark L. Brooks - Wabash IN
Keith E. Wilson - Wabash IN

Assignee:

GenCorp Inc. - Fairlawn OH

International Classification:

B29C 4706

US Classification:

15624411

Abstract:

A polymer laminate produced by crosshead extrusion suitable for wear resistant applications such as a vehile glass run channel comprises a layer of a weather resistant rubber such as an ethylene-propylenediene (EPDM) rubber and a layer of a wear resistant thermoplastic such as polypropylene. The laminate is passed through an oven at an elevated temperature sufficient to cure the EPDM rubber, for example, at about 375. degree. F. , with ambient temperature cooling fluid being blown over the exposed surface of the polypropylene thermoplastic. The interior polypropylene surface or interface is heated by the EPDM rubber which is at a high temperature as a result of the heat of extrusion and heat generated by cure thereof. As a result, the polypropylene interior surface or interface melts and causes it to flow and form a mechanical bond with the EPDM rubber while the exposed surface as well as a substantial portion of the polypropylene is kept from melting by the cooling fluid. The EPDM rubber can be extruded in the form of a channel having a longitudinal web which supports and is bonded to the laminated polypropylene wear strip to form a glass run channel.

International Classification:

B60R 1306

US Classification:

428122

Abstract:

A combined glassrun, greenhouse trim (10) for the window opening of an automotive vehicle comprising an extruded or co-extruded, polymeric glassrun (12) and a greenhouse trim (14). The greenhouse trim (14) is injection molded from a polymeric material against a surface of a flange portion (22) of the glassrun (12). The organic materials selected for the glassrun (12) and the greenhouse trim (14) are such that the greenhouse trim (14) is adhesively joined to the glassrun (12) during the injection molding of the greenhouse trim (14).

Assignee:

GenCorp Inc. - Fairlawn OH

International Classification:

B05D 500
B05C 320

US Classification:

427256

Abstract:

A coating apparatus and process for coating selected surface areas of extruded substrates with decorative or functional coatings by passing the extruded substrates emerging from the extrusion die through a coating block. The coating block contains a coating cavity die conforming to the selected surfaces to be coated wherein liquid coating is supplied to the coating cavity die in a manner to selectively coat the selected surfaces on the extruded substrate.
