The inner adhesive layer includes a first adhesive and an extender dispersed in the first adhesive, and the outermost adhesive layer includes a second adhesive that may be the same or different than the first adhesive.

Abstract: A member for use in undersea applications comprising a plurality of conduits assembled into a bundle; the bundle being wrapped with a pressure-sensitive tape comprising a backing, a layer of corrosion-resistant yarns on one surface of the backing, and pressure-sensitive adhesive layer that coats the corrosion-resistant yarns and binds them to the backing.

Abstract: Security tapes are disclosed that include a first substrate having a first major surface covered with a first PSA, a plurality of discrete pieces of second substrate laminated to the first major surface of the first substrate by the first PSA, and a second PSA applied to each of the plurality of discrete pieces of second substrate on a first surface opposite the first substrate. The first substrate is continuous in both the machine and transverse directions. Each discrete piece of second substrate has a length oriented in the transverse direction and may be spaced a distance apart, in the machine direction, from each adjacent piece of second substrate. The first adhesion of the first PSA for each of the discrete pieces of second substrate is less than a second adhesion of the second PSA for a packaging material or packaging carton.

Abstract: A testing device for testing adhesion seal strength of a tape to a substrate. The testing device includes a body defining a chamber having a first port in fluid communication with the chamber, a platform sealingly attached to the chamber and having an elongate opening or a plurality of openings therethrough as a second port of the chamber. The testing device further includes a frame removably mounted to the platform. The frame defines a perimeter that surrounds the second port and, when mounted to the platform, secures a test substrate thereunder against the platform with a fluid-tight seal. Methods for preparing a test sample and methods of operating the testing device are also disclosed.

Abstract: A method for continuous bulk polymerization is disclosed that includes providing a planetary roller extruder having a plurality of planetary roller zones, introducing an acrylate monomer, a di-vinyl monomer, and a hydroxyl functional acrylic monomer into the planetary roller extruder, introducing an initiator into the planetary roller extruder for initiation of a free-radical polymerization of the acrylate monomer, the di-vinyl monomer, and the hydroxyl functional acrylic monomer to form an acrylic polymer, maintaining the temperature of the free-radical polymerization in the planetary roller extruder below 240° C., and discharging a portion of the acrylic polymer from the planetary roller extruder, and returning the portion of the acrylic polymer to one or more of the plurality of planetary roller zones.

Abstract: Carrier films, adhesive tapes including the carrier film, hand tearable carton sealing tapes, and methods of making the same are described. The carrier films include a first layer of a polyethylene, and a second layer of a polypropylene coextruded therewith and biaxially oriented therewith. This carrier film has a first major surface and a second major surface. A pressure sensitive adhesive may be disposed on the first major surface of the carrier film to make an adhesive tape. The first major surface may be defined by the layer of polypropylene.

Abstract: Disclosed is a tape including a substrate having an adhesive layer applied thereto and an edge coating. The substrate and the adhesive together provide at least one masking edge where the edge coating is applied. The edge coating includes a flocculating agent. The edge coating provides the tape with enhanced masking ability.

Abstract: Disclosed is a tape that includes a substrate having an adhesive layer applied thereto, and an edge coating applied to a masking edge of the tape. The substrate and the adhesive, together, define a first and a second masking edge of the tape. The edge coating includes a flocculating agent that is a polyvalent metal salt or an ionic polymer. The edge coating improves the ability of the tape to provide a sharp mask line after a paint, a varnish, a paint stripper, or other coating composition is applied to a surface where the tape is adhered.

Abstract: Masking tapes that changes color when the tape is rubbed down or dispensed onto an adherend and methods of making such tapes are disclosed herein. The tape includes a backing, a layer of adhesive on the bottom surface of the backing, and a release structure on the top surface of the backing that includes a pressure-chromic indicator and a release layer. The pressure-chromic indicator is characterized in that it is not activated by the pressure applied during the manufacturing process, but is activated by the pressure applied when the tape is rubbed or dispensed onto an adherend.

Abstract: Disclosed is a tape including a substrate having an adhesive layer applied thereto and an edge coating. The substrate and the adhesive together provide at least one masking edge where the edge coating is applied. The edge coating includes a lipophilic agent, a flocculating agent, or combinations thereof. The edge coating provides the tape with enhanced masking ability by preventing paints, varnishes, paint strippers, and other coating compositions from infiltrating the tape substrate or the interface between the tape and an adherend.
