摘要:
A process for making a thermoformable conductive plastic laminate for use in making plastic parts adapted for electrostatic spray painting of a uniform high quality paint finish includes forming a matte release coated casting sheet, casting an electrically conductive polymer in thin film form on the casting sheet, drying to form a conductive primer coat, and transfer-laminating the conductive coating to a thin, thermoformable plastic face sheet. The matte release coat has a fine particulate filler that transfers a micro-roughened matte surface to the conductive primer coat. The conductive primer includes a polyester resin containing a fine particulate conductive material such as carbon black and, preferably, an anti-blocking agent such as fumed silica. The primer coated face sheet can be thermoformed and bonded to a underlying plastic substrate panel. The conductive primer has sufficient elongation and maintains uniform electrical surface conductivity and film thickness throughout the transfer-laminating, thermoforming and substrate panel-cladding process. The uniform surface resistivity of the conductive primer film is sufficient to permit electrostatic spray painting of the finished contoured panel and in one embodiment produces a Class "A" quality exterior automotive paint finish on the resulting panel.

A multilayer laminate such as a label assembly having high opacity and desirable appearance characteristics is described. The laminate includes a facestock layer, an adhesive layer, and a liner layer. The facestock layer includes a print-receiving top coat layer that includes a combination of titanium dioxide and one or more optical brighteners. The combination of these materials avoids build up of static charges upon laser printing on the facestock.

Polymeric compositions comprising polyvinylidene fluoride and one or more acrylic components are described. The compositions can be formed into films which do not require a carrier or other backing. Also described are methods for forming the films and applications for the films.

The present invention relates to a plastic panel construction with improved resistance to heat build. An outdoor weatherable panel comprises a substrate having an upper surface, a decorative layer disposed about the upper surface of the substrate, and a size coat layer disposed between the decorative layer and the substrate, where the size coat layer comprises an additive that is reflective to infrared radiation, ultraviolet radiation, or both. The additive can be a color pigment, a white pigment, a metallic pigment, or a combination of two of more thereof. The modified size coat layer provides a construction with excellent properties and improved resistance to heat build.

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.
