Abstract: Methods of bonding a pressure-sensitive adhesive to a substrate are provided. The methods include heating a styrenic block copolymer composition to provide an adhesive melt composition, wherein the styrenic block copolymer composition contains a hard segment block with a glass transition temperature of from 90°C to 220°C; masticating the adhesive melt composition; delivering the adhesive melt composition onto the substrate at a temperature that exceeds the glass transition temperature of the hard segment block by from 20°C to 150°C; and cooling the adhesive melt composition to obtain a bonded pressure-sensitive adhesive. Optionally, the substrate can be a non-film substrate, or the styrenic block copolymer composition can be provided in a core-sheath filament that includes a styrenic block copolymer core and a sheath that is non-tacky at ambient temperature.

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.

Abstract: Pressure-sensitive adhesive compositions and articles that include a layer of the pressure-sensitive adhesive compositions are provided. The pressure-sensitive adhesive compositions are particularly well suited for use with substrates that have been considered to have difficult to bond to surfaces such as those routinely encountered in the automotive industry. For example, the pressure-sensitive adhesive can be adhered to clear coat compositions, painted surfaces, and various polymeric materials having low energy surfaces (e.g., surfaces having a surface energy no greater than 35 dynes per centimeter).
