Various enhancements of heat seals are provided herein with sealant layers that provide for decreased chance of oversealing the heat seal to a container. Such enhancements include the use of various types of resins in combination to provide for desirable heating and sealing characteristics. Further, the heat seals may be especially suitable for use with polyester containers, such as those containing polyethylene terephthalate.

A bonded body is a bonded body in which a first metal member is bonded to a second metal member, where the first metal member is formed of a material having a hardness higher than that of the second metal member. The bonded body has a structure in which the second metal member is inserted into a protruded and recessed portion formed on a bonding surface of the first metal member, and the bonded body has a region in which the first metal member is in direct contact with the second metal member, and a gap between the first metal member and the second metal member is filled with a resin material.

A method of making a flexible pipe layer, which method comprises: commingling polymer filaments and carbon fibre filaments to form an intimate mixture, forming yarns of the commingled filaments, forming the yarns into a tape, and applying the tape to a pipe body to form a flexible pipe layer.

A microcapsule for use with an underwater adhesive includes a shell including nanoclay platelets and a polyurea product of an interfacial polymerization of a polyamine and an aromatic polyisocyanate. The microcapsule further includes a core composition encapsulated by the shell. The core composition includes a base catalyst for formation of a polyurethane, a polyol, and a hydrophilic solvent.

A solder material (30) for bonding a metal layer (20) to a ceramic layer (10), in particular for forming a metal-ceramic substrate as a carrier for electrical components, comprising: a base material and an active metal, wherein the solder material (30) is a foil comprising the base material in a first layer (31) and the active metal in a second layer (32), and wherein the foil has a total thickness (GD) which is less than 50 μm, preferably less than 25 μm and particularly preferably less than 15 μm.

Stretch-release adhesive articles with tunable mechanical properties are provided. The articles include a stretchable carrier extending along a first direction and including a first major surface and a second major surface opposite the first major surface. At least one of the first and second major surfaces of the stretchable carrier is a stretch-releasable adhesive surface, and the stretchable carrier includes a pattern of slits distributed thereon and configured to deform upon a stretch on the stretchable carrier to elongate the stretchable carrier.

Methods are described that include contacting an alkyl ammonium metal halide film with an alkyl ammonium halide, where the alkyl ammonium metal halide film includes a first halogen and a metal, the alkyl ammonium halide includes a second halogen, such that the contacting forms an alkyl ammonium metal mixed-halide film that interfaces with the alkyl ammonium metal halide film, where the alkyl ammonium metal mixed-halide film includes the first halogen, the second halogen, and the metal.
