A method for surface preparation of composite substrates prior to adhesive bonding. A curable surface treatment layer containing blocked isocyanate compounds is applied onto a curable composite substrate, followed by co-curing. The surface treatment layer may be a resin layer without fibers or a removal peel ply composed of resin-impregnated fabric. After surface preparation, the composite substrate is provided with a chemically-active, bondable surface that can be adhesively bonded to another composite substrate to form a covalently-bonded structure.

A joint between dissimilar thermoplastic materials comprising a first thermoplastic material layer; a second thermoplastic material layer having a melting point temperature different from a melting point temperature of the first thermoplastic material layer; and an interface layer coupled between the first thermoplastic material layer and the second thermoplastic material layer; wherein the interface layer is configured to join the first thermoplastic material layer and the second thermoplastic material layer together to form the joint, wherein the interface layer comprises a melting point temperature having a value selected from the group consisting of between the melting point temperature of the first thermoplastic material layer and the melting point temperature of the second thermoplastic material layer; or lower than the melting point temperature of the first thermoplastic material layer and the melting point temperature of the second thermoplastic material layer.

A method of bonding includes providing a thermoplastic substrate having a surface with a surface energy value of less than a 48 miliJoules per meter squared. The surface is exposed to particulate formed in a combustion flame from a precursor. The particulate forms an adherent layer of metal oxide on the surface. An adhesive is applied to the adherent layer. A second substance is placed in in simultaneous contact with the adhesive to bond the thermoplastic. A laminate is provided that includes a thermoplastic substrate having a surface. An adherent layer of metal oxide is on a surface of the thermoplastic substrate. An adhesive is attached to the adherent layer. A second substance is in simultaneous contact with the adhesive.

Provided are primer formulations for solvent cement bonding comprising cyclopentanone and, optionally, at least one additional organic solvent. The primer formulations are effective for solvent cement bonding plastic components together, wherein the plastic components may include ABS, PVC, or CPVC pipes and/or fittings.

Provided is a heater for a ciga-like electronic cigarette with a heat transfer efficiency improved by strengthening a bonding force between a cigarette support portion and a heater portion by thermally pressing and bonding the cigarette support portion and the heater portion together using a heat-dissipating adhesive layer with a heat-dissipating filler added to a high-heat-resistant thermoplastic polyimide resin, and a method of manufacturing the same.

A process for welding of at least two separate vehicle panels (12, 14) to form an integral part (16) for a vehicle. There is provided at least one first panel (12) including a first weld line area (18) and at least one second panel (14) including a corresponding second weld line area (19), the second weld line area (19) abutting in a weldable relationship to the first weld line area (18). The first and second weld line areas (18, 19) have at least one first weldable portion (22) and at least one second portion (24) at which welding is substantially hindered during welding attachment of the first and second panels (12, 14). The process includes applying a curable adhesive at each second portion (24), placing in a welding fixture and welding the panels (12, 14) at each first weldable portion (22) such that the panels (12, 14) are held together during curing of the adhesive.

A method for manufacturing a PDMS device in accordance with an exemplary embodiment of the present invention surface treats the entire surface of a pattern with a thiol group (—SH), so that a hydrogel may be connected to the surface of the pattern by a covalent bond under ultraviolet rays. Therefore, a PDMS device manufactured by the above method has an advantage in that the shape thereof may be stably maintained without the swelling or desorption of a hydrogel even when an electrolyte is filled in a pattern.
