A joint-sealing tape is useful for sealing building-structure joints, especially for sealing against sound and/or smoke and if necessary against fire. In particular, the joint-sealing tape is suitable for sealing a joint between a first building part and a second building part, with a sealing element and an adhesive layer, which sealing element has a predetermined geometry. Furthermore, a sealing arrangement contains such a sealing tape and is suitable for sealing of building structure joints, especially for sealing against sound and/or smoke and if applicable against fire.

A sealing element includes a carrier layer having a first and a second major surface, a pressure sensitive adhesive layer having a thickness of at least 100 m, and optionally a release liner covering at least a portion of an outer major surface of the pressure sensitive adhesive layer facing away from the carrier layer, wherein the carrier layer includes at least one elastomer E and/or at least one thermoplastic vulcanizate TPV and has a thickness of at least 0.2 mm.

Disclosed herein are two-component polyurethane adhesive systems comprising a mixture of primary and secondary diamines.

A method for treating an aromatic polyamide filament or yarn to improve its adhesion to rubber wherein, the method comprises exposing the filament or yarn to a first mixture of reagents comprising multi-functional isocyanate oligomers and multi-functional epoxy oligomers, wherein the ratio of total isocyanate groups to total epoxy groups in the mixture is in the range of from 0.8 to 1.2, and heating the exposed filament or yarn to a temperature of at least 100 degrees C. whereby the epoxy and isocyanate oligomers cross-link and form a network on the surface of the filament or yarn.

Arrangements related to carbon flocked tape are described. The flocked tape can include a first adhesive, a substrate, a second adhesive, and a plurality of fibers. The substrate can be formed from any suitable metal, polymer, and/or natural material. The fibers can be formed from milled recycled carbon fibers. The carbon fibers can be connected within the tape via an electrostatic flocking process. The flocked tape can allow for application, removal, and re-application. The carbon flocked tape can provide several benefits, such as electric and/or thermal conductivity, noise and vibration reduction, insulation and shielding, and altered fluid dynamics.
