The invention relates to compositions comprising at least one first and one second component; —the first component K1 comprising at least one di(aminobenzoate) ester A1 of formula (I) with an average molecular weight of 500 g/mol to 2000 g/mol, preferably 600 g/mol to 1500 g/mol and particularly preferred between 650 g/mol and 1300 g/mol, G being a divalent group derived from poly(tetramethylene oxide) diol, and —the second component K2 comprising at least one aromatic polyisocyanate B1 with an average molecular weight of 160 g/mol to 1100 g/mol, preferably 500 g/mol to 800 g/mol.

A joined body of the embodiments is a joined body which includes copper and resin, wherein in a joint surface of the copper to the resin, a triazine thiol derivative, or the triazine thiol derivative and a silane coupling agent are bonded to a base surface and the silane coupling agent is bonded to an oxide film formed on part of the joint surface, respectively, and the copper and the resin are molecularly joined to each other. This configuration makes it possible to obtain a joined body having high reliability by molecularly joining both the base surface and the oxide film of the copper, and the resin securely and achieving a strong joint of the copper and the resin at a time of joining the copper and the resin even though the oxide film is formed on part of the joint surface of the copper.

Double-sided reworkable pressure sensitive adhesive tape joins electronic device structures. The reworkable pressure sensitive adhesive tape has a pair of polymer carrier layers that are attached to each other using a thermoplastic adhesive. Opposing outer surfaces of the carrier layers are coated with pressure sensitive adhesive. The thermoplastic material that is used in attaching the carriers to each has a softening temperature that allows the thermoplastic material to be softened without significantly softening the carrier layers. When the thermoplastic material is softened, the structures that have been joined using the tape may be separated from each other. This divides the tape into two tape remnants. After cooling the tape remnants to restore cohesive strength to the pressure sensitive adhesive, the tape remnants can be cleanly peeled away from the structures. Additional reworkable tape may then be used to reattach the structures.

Disclosed are powerful adhesive tapes, which rapidly coat rough and/or curved surfaces with different surface energies and thereby build up high adhesion. The adhesive joints formed in this way furthermore have good shear strength, even at elevated temperatures. Finally, enduring mechanical loading on the adhesive joints does not lead to the adhesive tape peeling from the surface. This is achieved with an adhesive tape comprising at least one foamed layer and at least one adhesive compound layer, wherein the adhesive compound layer contains at least one poly(meth)acrylate, and the poly(meth)acrylate is cross-linked with at least one covalent and at least one coordinative cross-linker.

An adhesive formulation such as a hot melt adhesive or a pressure sensitive adhesive is provided comprising 5 to 98% (by weight) biodegradable substantially non-crystalline mcl-PHA. The mcl-PHA may be cured with a peroxide curing agent. The adhesive formulation may include an additional biodegradable polymer, or a non-biodegradable thermoplastic elastomer. Hot melt adhesives comprising significant amounts of biodegradable mcl-PHA, waxes, and tackifiers are also provided.

The present application provides methods and compositions for patching a polymer or a non-polymer substrate surface by producing a bond between a polymer patch surface and the substrate surface. The application also provides kits having instructions for patching a polymer or a non-polymer substrate surface by producing a bond between a polymer patch surface and the substrate surface.

Devices and methods covering a gap between an edge of a surface and a body exposed through an opening in the surface defined by the edge. Such a device has at least first and second sections formed of different materials. The device is positioned so that the second section is over a portion of the surface adjacent the opening and the first section extends over the gap and the opening. After removing a release liner releasably secured to a backside of the first section to cover an adhesive, portions of the first section are bent and molded to plastically conform the portions to the edge of the surface while the second section remains over the portion of the surface adjacent the opening. The body is then contacted with the backside of the first section such that the backside of the first section is adhered to the body with the adhesive.

The invention is directed to masking tapes comprising reference lines that facilitate the use of adjacent edges or other linear features to place masking tape edges on irregular or curved boundaries between surfaces.
