A method of manufacturing a coated article comprises injecting a feedstock with a polymer resin to provide a resin-injected feedstock, pulling the resin-injected feedstock through a pultrusion die to form a pultrusion substrate having one or more profile surfaces, adhering an adhesive material comprising a thermoplastic polyurethane onto at least a portion the one or more profile surfaces to form one or more adhesive tie layers on the pultrusion substrate, and applying one or more coating materials onto the one or more adhesive tie layers to form one or more coating layers on the one or more adhesive tie layers to provide a coated pultrusion article, wherein an adhesion strength between the one or more coating layers and the one or more adhesive tie layers is higher than a corresponding adhesion strength would be between the one or more coating layers and the pultrusion substrate.

The present invention provides a multi-layer hose comprising a cover layer, comprising a first polymer, an enhancement layer comprising woven filaments, and an inner lining, comprising a second polymer, wherein the first polymer and the second polymer are dissimilar. The first polymer is preferably a polymer with good wear resistance properties, e.g., thermoplastic polyurethane (TPU), TPU/PVC, or PVC, or PVC/NBR. The second polymer is preferably a polymer with good chemical resistance properties, e.g., ethylene propylene diene monomer (EPDM) rubber. The present invention also provides a method of manufacturing said multi-layer hose.

A contact nozzle for simultaneously coating a plurality of elastic strands moving in a machine direction with an adhesive is described. The contact nozzle includes a single fluid inlet for receiving the adhesive from a fluid module, a first inverted V-shaped notch, a second inverted V-shaped notch, a third inverted V-shaped notch, and a mounting surface configured to abut the fluid module when the contact nozzle is coupled to the fluid module. Each inverted V-shaped notch extends along the contact nozzle in the machine direction, has an open bottom end, a circular closed top end. Each inverted V-shaped notch includes an adhesive orifice in fluid communication with the single fluid inlet for receiving the adhesive for directing the adhesive into contact with an upper surface of an elastic strand.

In various embodiments, a hot melt device comprising a heating device that is automatically or manually triggered is configured so as to have its melt surface applied bringing a thermoplastic material in its solid form into contact with a surface via mechanical extrusion; using a heater to heat the thermoplastic material to a temperature above a melting temperature of the thermoplastic material while maintaining the contact of the thermoplastic material with the surface; allowing the heated thermoplastic material to cool to a temperature that is below the thermoplastic material's melting temperature; and allowing the heated thermoplastic material to bond the hot melt apparatus to the contacted surface without a solvent or use of a curing chemical reaction when the heated thermoplastic material is cooled to below the thermoplastic material's melting temperature while remaining connected to the structural body.

A portable glass repair kit system and method, more particularly, for windshield repair for laminated glass and the like to provide an easy to use, highly portable, and economical glass repair kit. The glass repair kit does not require specialized equipment such as an injector, plugger device, suction cups, or require any additional tools or specialized knowledge of how to use the repair kit. The glass repair kit contains a resin which may be urged by a user through slight pressure after the glass repair kit is adhered over an impact point and any cracks thereby repairing a windshield in a more cost effective, time efficient, and user friendly way.

A nozzle assembly may be used to apply fluid to an advancing substrate. The nozzle assembly includes a nozzle body made from a first material. The nozzle body may include one or more abrasion resistant materials fused to the nozzle body. The nozzle body may be configured to deposit a fluid, using a shim plate, onto the advancing substrate. As the substrate advances past the nozzle assembly, the substrate and/or the fluid may contact the nozzle assembly resulting in wear. The one or more abrasion resistant materials, which is different than the first material of the nozzle body, may be fused to a portion of the nozzle body to reduce the wear and prolong the life of the nozzle body. Thus, the portion of the nozzle body having the abrasion resistant material is restored rather than having to replace the entire nozzle body.

A method of producing a plate-like construction having a double-wall structure and its use. According to the present invention, several elongated profiles which have essentially straight central axes are arranged against each other in such a way that adjacent hollow profiles abut each other and together form, in general terms, a flat stack having two opposite sides. The hollow profiles are welded together in order to join them with welded seams, in which case the welding is essentially carried out simultaneously from both sides of the stack. Besides good flexural strength and the opportunity to recycle, thermoplastic plates which are produced by means of the present method exhibit resistance to corrosion, decay and mould.

Disclosed herein are exemplary embodiments of linings, liners, and methods of providing a liner or lining for a tank. An exemplary embodiment includes a method of providing a liner or lining for a tank. In this exemplary embodiment, the method includes extrusion welding a pair of sheets together by infusing a molten thermoplastic material along an interface and within a gap between the pair of sheets. The method also includes extrusion welding the pair of sheets to a bottom sheet by infusing the molten thermoplastic material along and between the pair of sheets and the bottom sheet.

Systems useful for reinforcing a support mat over at least one seam formed between upper and lower panels of the mat include at least one extruder configured to apply weld-forming material over the seam(s) to form at least one weld atop the seam(s) and at least one electronic controller associated with the extruder.

A method of contact coating at least one elastic strand with an adhesive is disclosed. A first strand has a periphery with an upper surface. The first strand is moved in a machine direction relative to a contact nozzle, the adhesive is discharged from the contact nozzle into contact with the upper surface of the first strand, and pressurized air is discharged at the adhesive on the first strand to cause the adhesive to spread around the periphery of the first strand without blowing adhesive off the first strand.
