Abstract: Methods of bonding together substrates that do not require use of primers, mixing, fixturing, or autoclaving. These methods can include the steps of disposing an adhesive layer on a bonding surface of either substrate, the adhesive layer comprising a curable composition that is dimensionally stable at ambient conditions; either before or after disposing the adhesive layer on the bonding surface, irradiating the adhesive layer with ultraviolet radiation to initiate curing of the curable composition; placing one substrate so as to be bonded to the other substrate by the adhesive layer; and allowing the adhesive layer to cure.

Abstract: Methods of bonding hardware to glass and other substrates are provided that do not require use of primers, mixing, fixturing, or autoclaving. These methods include the steps of disposing an adhesive layer on a bonding surface of either the hardware or the vehicular glass, the adhesive layer comprising a curable composition that is dimensionally stable at ambient conditions; either before or after disposing the adhesive layer on the bonding surface, irradiating the adhesive layer with ultraviolet radiation to initiate curing of the curable composition; placing the hardware so as to be bonded to the vehicular glass by the adhesive layer; and allowing the adhesive layer to cure.

Abstract: The present disclosure provides a core-sheath filament. The core-sheath filament includes an adhesive core and a non-tacky sheath, wherein the sheath exhibits a melt flow index of less than 15 grams per 10 minutes. The present disclosure also provides a method of printing an adhesive. The method includes a) melting a core-sheath filament in a nozzle to form a molten composition, and b) dispensing the molten composition through the nozzle onto a substrate. Steps a) and b) are carried out one or more times to form a printed adhesive. The core-sheath filament includes an adhesive core and a non-tacky sheath. Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an article; and generating, with the manufacturing device by an additive manufacturing process using a core-sheath filament, the article including a printed adhesive based on the digital object. A system is also provided, including a display that displays a 3D model of an article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an article including a printed adhesive, using a core-sheath filament.

Abstract: Provided is an apparatus for dispensing a composition that includes a barrel having an inlet and outlet, an extrusion screw, and a drive mechanism operatively coupled to the extrusion screw. The extrusion screw includes a shaft having a shank end for connection to the drive mechanism and a distal end opposite the shank end. A first helical flight extends around a first section of the shaft, and a second helical flight extends around a second section of the shaft. The second section is located distal to the first section and the first helical flight has a nominal outer radius less than that of the second helical flight, and optionally the first helical flight has a pitch shorter than that of the first helical flight.

Abstract: A core-sheath filament including a crosslinkable adhesive core that can be cured using ultraviolet or visible light radiation. These crosslinkable adhesive core compositions can provide very high bond strength and are capable of replacing traditional mechanical fasteners in many industrial applications. Core-sheath filaments including such crosslinkable compositions, crosslinked compositions, articles containing these compositions, and methods of making the articles are provided. The crosslinkable compositions contain pendant aromatic ketone groups or pendant (meth)acryloyl groups that, upon exposure to ultraviolet radiation, result in the formation of crosslinks within the polymeric material. The crosslinked compositions can function as pressure-sensitive adhesives.
