The invention relates to a sealing element with high sealing effect against air and moisture, which is easy to apply, and which moreover offers the possibility to reopen the sealed gap in an uncomplicated manner. Said solution is provided by an adhesive tape with differing adhesive power on the two main sides, which comprises a) a polymer foam layer and b) an outer adhesive compound layer and/or an outer thermoplastic film on one side of the polymer foam layer and is characterized in that, where the adhesive tape comprises an outer adhesive compound layer, the tape has a greater adhesive power on the side provided with the outer adhesive compound layer than on the opposing side and/or, where the adhesive tape comprises an outer thermoplastic film, the tape has a lower adhesive power on the side provided with the outer thermoplastic film than on the opposing side. The invention furthermore relates to the use of an adhesive tape according to the invention for sealing a joint between two components.

To provide a double-sided adhesive tape that achieves both high adhesive force and excellent easy disassembly properties. The double-sided adhesive tape includes a first adhesive layer; an intermediate layer provided on the first adhesive layer and containing a pigment and a binder resin; a film-like substrate stacked directly on the intermediate layer; and a second adhesive layer provided on the film-like substrate, in which the content of the pigment is from 1 to 85 wt % based on the total mass of the intermediate layer.

A composition that toughens and impact modifies epoxy resin based compositions comprising one or more co-polyamides and one or more block copolymers with polyamide and polyether blocks. The disclosure also relates to epoxy resin compositions containing the composition comprising one or more co-polyamides and one or more block copolymers with polyamide and polyether blocks and films, adhesives, foamable compositions and foamed compositions containing such a composition.

Primer for producing a partable adhesive bond, the primer being based on a pressure-sensitive adhesive which comprises a chemical or physical blowing agent.

Tape constructions having a pressure sensitive adhesive containing a block copolymer component that includes a midblock segment and a plurality of end block segments, each end block segment comprising polystyrene, a (meth)acrylic functional additive having a glass transition temperature of from 50° C. to 160° C., a first tackifier compatible with the midblock segment and containing a hydrocarbon, and a second tackifier compatible with the end block segments and containing a polyphenylene ether that can be incorporated into articles. The pressure sensitive adhesive is subjected to electron beam radiation.

Peel-away tape includes a double-sided adhesive tape with a perforated design and a peel-away backing that includes liftable tabs to assist in the removal thereof. In an exemplary embodiment, the tape and peel-away backing is perforated on equidistant intervals. A small tab located at the center of each perforation extends over the perforation line which, when separated, extends outward where it can be grasped.

The present invention relates to a redetachable adhesive tape having a carrier based on a crosslinked polyurethane and an adhesive layer based on vinylaromatic block copolymer, to a method for producing the adhesive tape and the use of the adhesive tape in the production of electronic components.

The present invention relates to a tyre (11) having an inner surface (111) and provided with at least one monitoring device (3) adhering to said inner surface (111), wherein said monitoring device (3) is made on a flexible support, and wherein the adhesion of said flexible support to said inner surface (111) is achieved through a decoupling element (4) interposed between said at least one monitoring device (3) and said inner surface (111) of the tyre (11).

A joint-sealing element for sealing building-structure joints is described, especially for sealing against sound and/or smoke and if necessary against fire. In particular, a joint-sealing element for sealing on a building construction and/or on a building structure is described, especially for sealing a joint between a first building part and a second building part, with a carrier element and a sealing profile disposed on this carrier element, wherein the disposed sealing profile has a predetermined geometry.

Furthermore, a sealing arrangement as well as a method for sealing building-structure joints is described, especially for sealing against sound and/or smoke and if necessary against fire, with such a joint-sealing element.

The present invention relates to an adhesive tape comprising at least one carrier that has a thickness of 20 to 250 μm, preferably 50 to 150 μm, and has at least one layer (i) based on preferably uncrosslinked thermoplastic polyurethane that has been produced by means of extrusion, wherein the polyurethane is based on aromatic polyisocyanate, such as aromatic diisocyanate in particular, or (ii) based on preferably uncrosslinked polyurethane that has been produced from a dispersion, wherein a pressure-sensitive adhesive layer is disposed on at least one side, preferably both sides, of the carrier. The invention also relates to processes for producing the adhesive tape and to the use thereof for bonding of components in electrical, electronic, optical or precision mechanical devices, such as, in particular, of windows or lenses in housings of precision mechanical, optical and/or electronic devices.
