Publication number: 20020041964Abstract: A method is provided for manufacturing a painted plastic component having a badge, emblem or other ornamentation, such as air bag covers having a badge, or wherein the component is the badge itself. The method includes providing a painted film sheet and a one-piece thermoplastic elastomeric structural carrier. A bottom contact surface of the film sheet bonds with a front contact surface of the structural carrier by diffusion between the contact surfaces thereof within a mold cavity of an injection mold separate from the mold cavity of a vacuum mold which is utilized to vacuum-mold the film sheet to form the desired painted plastic component.Type: ApplicationFiled: November 30, 2001Publication date: April 11, 2002Applicant: Patent Holding CompanyInventors: Larry J. Winget, Darius J. Preisler, Jason T. Murar

Patent number: 6329060Abstract: A multi-component composite coating composition is provided which includes a pigmented base coat and a transparent topcoat composition applied over the base coat. The transparent topcoat is deposited from a substantially solvent free film-forming composition which includes a thermosettable dispersion of polymeric microparticles having functionality adapted to react with a crosslinking agent and a hydrophilic crosslinking agent reactive with the functionality of the microparticles. The microparticles are prepared from one or more reaction products of ethylenically unsaturated monomers, one or more hydrophobic polymers and one or more hydrophobic crosslinking agents. Pigmented film-forming compositions as well as curable compositions containing the above-described dispersions also are provided. A method of forming the dispersion of polymeric microparticles is provided.Type: GrantFiled: November 10, 1999Date of Patent: December 11, 2001Assignee: PPG Industries Ohio, Inc.Inventors: Karen A.

Pressure and vacuum-deformable, grained bonding foil, method for its manufacture and its utilization
Publication number: 20010028957Abstract: The invention relates to a pressure and vacuum deformable, grained bonding foil for linings of motor vehicle interiors with at least one support layer, a single or multi-layer bed of polyurethane, and also, if applicable, an adhesion facilitator layer, arranged in between, a primary layer and also additional conventional layers, whereby the layer of polyurethane has a Shore D Hardness of less than 50, specifically less than approximately 48. Subject of the invention is also a method for the manufacture of the bonding foil as well as its utilization for lining the interiors of motor vehicles. Said bonding foil demonstrates excellent manipulation properties and presents outstanding physical/mechanical properties, such as excellent breaking elongation, grain stability, scratch resistance, high resistance to wear and tear, high UV-resistance, excellent solvent resistance as well as very high thermal aging resistance.Type: ApplicationFiled: February 20, 2001Publication date: October 11, 2001Inventors: Ulrich Breuksch, Hans-Hinrich Kruse, Claus Zurbig -
Patent number: 6299974Abstract: The present invention is directed to a barrier layer which has the ability to substantially prevent the diffusion of stains, such as plasticizers and dyes or other chemicals, onto a surface of a surface covering, from a surface or object in which the surface covering is placed upon. The barrier layer contains a polyamide or polyurethane and is preferably located above a substrate or base layer in a surface covering. The barrier layer preferably is located between a UV topcoat layer and a vinyl wear layer. The present invention also relates to a method of preventing stain migration onto a surface covering from a surface on which the surface covering is placed by use of the barrier layer of the present invention and also relates to methods of making surface coverings containing the barrier layer of the present invention.Type: GrantFiled: September 17, 1999Date of Patent: October 9, 2001Assignee: Mannington Mills of Delaware, Inc.Inventors: Keith S.

Patent number: 6280847Abstract: An intrusion resistant laminated glazing, suitable for automotive use, comprises an impact resistant ply of rigid thermoplastic polyurethane sensitive to ultra-violet radiation and, outside said ply, an ultra-violet absorbing or reflecting ply. The ultra-violet absorbing ply may be of thermoplastic polyurethane interlayer material which serves to bond the rigid thermoplastic polyurethane ply to outer glass plies. By using interlayer materials of low modulus to bond the rigid thermoplastic ply to outer glass plies, a product with good impact resistance and intrusion resistance is achieved.Type: GrantFiled: May 1, 1998Date of Patent: August 28, 2001Assignee: Pilkington PLCInventors: Philip Harold Corkhill, Malcolm Francis Green, Neil Winstanley, Paul Arthur Holmes
