摘要:
A process for making a protective and decorative surfacing film comprises extrusion coating a solventless polymeric material from an extruder die to form an optically clear first layer on a polyester carrier sheet traveling past the extruder die opening. The extrusion coated first layer is immediately cooled on the carrier sheet to harden it, followed by applying a pigmented second layer to the first layer. The composite paint coat is transferred to a reinforcing backing sheet, after which the carrier sheet is separated from the paint coat to expose the outer surface of the first layer as a high gloss surface with a high distinctness-of-image, providing a transparent protective outer coat for the pigmented second layer. The pigmented second layer can be solvent cast and dried or extruded and hardened as a separate coating on the first layer. The composite paint coat can be bonded to a coextruded size coat and semi-rigid plastic substrate panel to form a thermoformable laminate. Techniques are disclosed for producing extruded clear films of exceedingly high optical clarity using a closed air flow transport and HEPA filtration system that removes airborne particles from the resin handling and extrusion process, thereby preventing micron-sized contaminants naturally present from many sources from entering the process and degrading ultimate film quality.

摘要:
A process for making a protective and decorative surfacing film comprises extrusion coating a solid polymeric material to form an optically clear first layer (10) on a smooth surface of a carrier sheet (12). The extrusion coated first layer is immediately cooled, followed by applying a pigmented second material (22) in thin film form. The composite paint coat is then transferred to a supportive backing, after which the carrier sheet is removed to expose the high gloss outer surface of the first layer. The second layer may be solvent cast, extrusion coated, or coextruded with the first layer.
摘要:
A process for making a protective and decorative surfacing film comprises extrusion coating a solid polymeric material from an extruder die to form an optically clear first layer of uniform film thickness on a smooth surface of a carrier sheet traveling continuously past the extruder die opening. The extrusion coated first layer is immediately cooled on the carrier sheet to harden it, followed by applying a pigmented second layer in thin film form to the first layer to form a composite paint coat in which the first and second layers are bonded to each other. The composite paint coat is then transferred to a supportive backing sheet or substrate panel, after which the carrier sheet is separated from the paint coat, to expose the outer surface of the first layer as a high gloss surface with a high distinctness-of-image, providing a transparent protective outer coat for the underlying pigmented second layer. The pigmented second layer can be solvent cast and dried or extruded and hardened as a separate coating on the extrusion coated first layer. Alternatively, the second layer can be formed with the first layer as a coextrusion which is extrusion coated onto the smooth surface of the release coated carrier sheet that travels past the extruder die.

摘要:
A flexible decorative sheet for use in surfacing an automobile body panel includes a first polyester carrier sheet having a high gloss surface, a clear coat of a weatherable optically-clear polymer containing fluorocarbon resin and an acrylic resin coated on the surface of the first carrier sheet, a tie coat on the clear coat, and a color coat containing a chlorinated polymer with dispersed pigments cast on the tie coat and dried. A pressure-sensitive adhesive layer is formed on a second polyester carrier sheet and then laminated to the exposed face of the color coat to form a pressure-sensitive, adhesive-backed composite paint coat between the outer carrier sheets which form protective removable backing sheets for the resulting laminate. The decorative sheet is applied to a substrate panel by pressure-sensitive adhesive bonding techniques, with the clear coat serving as a glossy, weatherable protective outer layer for the underlying color coat. The PVC-containing color coat enhances room temperature elongation of the finished film to enable application of the laminate to three-dimensionally contoured surfaces. The resulting paint finish has a defect-free, weatherable and durable outer surface with high gloss and high distinctness of image, meeting requirements for exterior automotive use.
摘要:
An exterior automotive quality paint coat is laminated to the surface of a plastic car body member of panel. A dry paint transfer film is first laminated to a relatively thin semi-rigid thermoformable resinous backing sheet. The backing sheet side of the resulting laminate is then laminated to a relatively thick thermoformable substrate sheet comprising the same or a compatible polymeric material. The two sheets are joined by extruding the thick substrate sheet and using the heat of extrusion to then laminate the thin backing sheet to the thicker extruded substrate sheet. The resulting thick sheet laminate is then thermoformed, preferably by first heating the laminate to a forming temperature, followed by vacuum forming the laminate to a three-dimensional shape of the finished automotive part, such as a facia, ready to put on a vehicle.
