Abstract: This invention relates to a method of creating a seamless printing master for use with an embossing roll to ultimately produce a textured wall or floor covering. A hardenable material is applied to the textured surface of a positive printing master section. The positive printing master section is pressed onto the embossing roll and the hardenable material is allowed to cure to a hardened state. The positive printing master section is then removed to expose a negative printing master region which is the negative image of the pattern contained in the positive printing master section, imprinted in hardened material, and adhered to the embossing roll. The process is repeated, either reusing the original positive printing master section or using a different positive printing master section, overlapping positive printing master sections onto previously formed negative printing master regions until the entire outer surface of the embossing roll is covered.

Abstract: An anti-fracture, water-resistant, masonry-bondable membrane comprises a lamina having a central layer generally containing at least one ply of a flexible material, e.g., an organic polymer such as polyvinyl chloride, generally in the form of a sheet, and a nonwoven fiber layer physically bonded to each side thereof. The formation of the lamina is generally accomplished by laminating a single, nonwoven layer to a layer or sheet of a flexible material in the presence of heat and pressure to produce a construction wherein the nonwoven fibers are partially embedded in the flexible material. Subsequently, two such constructions are bonded together under heat and pressure to produce essentially a four-ply lamina wherein the layers of flexible material such as a polymer are fused to one another.

Abstract: Polymeric blends suitable for making plastic sheets and laminas which exhibit improved flexural durability while retaining stiffness and impact strength include a core made from a blend comprising polyvinyl chloride resin, a vinyl chloride-vinyl ester copolymer, one or more acrylic polymers or copolymers, a chlorinated polyolefin, a solid tin stabilizer, and one or more ester waxes. The lamina, which is suitable for use as an extended life credit card, is prepared by forming a polymeric blend of a core material into a base layer sheet material which is subsequently treated to reduce surface tension and improve ink adhesion thereto, then printed with desired indicia, and finally provided with a contact-transparent protective overlay which is laminated thereto.

Abstract: A sealing unit for a movable window of a vehicle. The sealing unit includes a one-piece, elongated, flexible sealing member having a first portion for mounting the sealing unit to a frame of a vehicle and a second portion for receiving the movable window, and a flexible, decorative trim associated with a surface of the sealing member that is viewable from the exterior of the vehicle when the sealing unit is mounted to the frame. Both the sealing member and the decorative trim are sufficiently flexible to permit the sealing unit to conform to the contour of the frame when the sealing unit is mounted to the frame in a single mounting operation to provide a substantially continuous seal between the frame and the sealing unit.

Abstract: A process for repairing surface defects in plastic articles, especially plastic articles formed from fiber reinforced thermosetting resins, includes the steps of applying a powder coating composition to a defective area on the surface of a plastic article, curing the applied powder coating composition through the application of heat, and removing excess cured powder coating composition from the area of the defect to conform the area of the defect to the proper contours of the plastic article. The process can be utilized for repairing surface defects such as porosity, scratches, gouges and sand-through areas of cured thermoset substrates such as automotive body panels formed from sheet or bulk molding compounds.

Abstract: A one-package primerless structural adhesive is disclosed that is particularly well suited for adhering one or more substrates of fiber-reinforced plastics. This adhesive uses dicyandiamide, its substituted derivatives, or melamine as the principal curative. A polyisocyanate prepolymer is made from various polyols reacted with polyisocyanates. In the absence of moisture, the curative and polyisocyanate can coexist in a single package without reacting for periods of time in excess of four months. Upon heating the adhesive to 150.degree. C., it cures in about five minutes or less, forming an initial structural bond that after heat aging is often stronger than the cohesive strength of the fiber reinforced substrate.

Abstract: This invention relates to a method of creating a seamless printing master for use with an embossing roll to ultimately produce a textured wall or floor covering. A hardenable material is applied to the textured surface of a positive printing master. The embossing roll is placed on the positive printing master and then rolled in a forward direction, compressing the hardenable material between the textured surface of the substrate and the outer surface of the embossing roll, until approximately three fourths of the circumference of the embossing roll is covered. The hardenable material is then allowed to harden. A second amount of hardenable material is applied to the portion of the positive printing master which corresponds to the uncovered portion of the embossing roll.
