Abstract: The invention is a patch system for repairing collapsible fuel tanks, water tanks, inflatable boats, and other articles fabricated from a flexible structural fabric coated with a polymer. The coated structural fabric is made of nylon or polyester synthetic fibers or a blend thereof, which are coated with a thermoplastic elastomer. The structural coated fabric is coated with a thermoplastic elastomer that is a urethane (TPU), or a TPU alloy polymer. Likewise, the patch is a urethane adhesive having a latent cure coated on a TPU film. The patch can also have an integral reinforcing fabric for applications requiring a higher tensile patch. In the invention, the urethane adhesive of the patch is solvent activated by the application of a thin coating of a volatile, substantially low odor, fugitive solvent like acetone or MEK. While in the activated state, the adhesive has much less cyrstallinity and a lot more tack.

Abstract: The invention is a heat curable extruded adhesive laminate system for producing collapsible tanks. The laminate is a composite of a fabric; an extruded linear hydroxyl adhesive having an uretdione that serves as a latent thermally activated curing component, and a high cyrstallinity thermoplastic polyurethane. In the system, panels cut from the adhesive laminate are assembled and seamed in a compression press operating at about 260° F. to about 350° F. The bonding process takes about 20-45 minutes, which causes the latent thermally activated curing component to cure the adhesive. Following compression heating in the press, the resulting seams have a strength that exceeds the minimum acceptable performance of 25 lbs/in, after being immersed in water and/or fuel at 160° F. for six weeks.

Abstract: The invented product is a fleecebacked laminate that is suitable as a single-ply fleecebacked roofing membrane. The laminate consists of the following: 1) a thermoplastic reinforced planar sheet, 2) a needle punched fleece formed on both sides of the thermoplastic reinforced planar sheet, and 3) a thermoplastic polymeric layer extruded onto one side of the fleece. The fleece is formed by needle punching fibers through the reinforced planar sheet. The reinforced planar sheet serves as a common supporting base the resulting two-side fleece. The thermoplastic polymeric layer is embedded with one side of the fleece fibers. The thermoplastic polymeric layer serves as the top layer of the roofing membrane, and the second side of exposed fleece serves as a felt. The thermoplastic polymeric layer is preferably comprised of an extruded PVC substrate, compounded to have excellent weather resistance, printability and to be nonflammable. The fleece fibers are preferably composed of polyester.

Abstract: A composition of a compounded PVC substrate that is suitable as an extrudate in very wide extruders. The composition is for use as a coating on scrim in the manufacture of billboards, wherein the composition does not yellow or burn, even in extruders having a die 215 inches wide (5,486 mm) with a 1.5 to 2.0 mm lip opening average. The composition has excellent printability, weather resistance and a price point that is low enough to meet competition. The composition has minimal quantities of lubricants and other processing aids, and utilizes a PVC suspension resin having high porosity. The invention enables the fabrication of printable billboard sheeting that is seamless.

Abstract: A message display is described having a message display surface with a first area. At least one hook fastening element with a second area is affixed to the message display surface. The message display also includes at least one message display panel with a third area. The display panel has a printable surface and an entangled fiber sheet backing. The at least one hook fastening element engages the entangled fiber sheet backing to maintain the at least one message display panel in a fixed relationship to the message display surface. A message display construction system and a method of creating a message display are also described.

Abstract: Roofing of plastic sheet (preferably very flexible polypropylene) has embedded in it reinforcing threads of a higher tenacity (preferably ultra high molecular weight polyethylene) in a narrow mounting area along a panel edge, and other threads of lower tenacity in other areas of the panel (and preferably in the mounting area as well), the threads being preferably weft-knitted with nine by nine thread count throughout.

Abstract: Signs which include a sheet including plastic stiff enough to resist fracture and flexible enough to maintain surface flatness in use without being put under tension, and such sheets.

Abstract: Graphic laminar sheet material in which a barrier layer separates a base layer and an eradicable layer of color contrasting with the base layer.
