The invention provides an assembly for fuel cell which has an excellent adhesive force in the presence of hot water, and a laminated body which is used for the assembly for fuel cell. The assembly for fuel cell comprises an adhesive resin layer containing a polyolefin having at least one group selected from the group consisting of an acidic group and an acid anhydride group and having an acid value of 0.01 mgKOH/g to 6.5 mgKOH/g; and two or more members bonded with the adhesive resin layer interposed therebetween, wherein at least one of the members is a metal member having a ratio of a dipole term in surface free energy of 0.01% to 5.0%.

Assembly for fuel cell, and laminated body

An adhesive composition includes an acid-modified polyolefin (A) that is graft-modified with 0.2 to 5 parts by mass of an acid compound (a2) with respect to 100 parts by mass of a polyolefin (a1), in which the adhesive composition has a storage modulus of from 130 to 330 MPa at 23° C. as measured by a rheometer and has a yield modulus of from 30 to 120 MPa at 23° C. in a tensile test.

Adhesive composition, film-like adhesive and multilayer film

The invention provides a laminated body having an excellent adhesive force with respect to a low-polarity metal member in the presence of hot water. The laminated body contains a resin substrate; an easily adhesive layer provided on at least one surface of the resin substrate; and an adhesive resin layer provided on a surface of the easily adhesive layer on a side opposite to the resin substrate, wherein the adhesive resin layer contains a polyolefin having at least one group selected from the group consisting of an acidic group and an acid anhydride group and having an acid value of 0.01 mgKOH/g to 6.5 mgKOH/g; and the laminated body is used for bonding a metal member having a ratio of a dipole term in surface free energy of 0.01% to 5.0%.

Laminated body

An adhesive composition having high room-temperature peel strength, high hot peel strength, and excellent adhesion, as well as excellent electrolyte resistance even when used for packaging materials for lithium ion batteries is provided, which contains an organic solvent, a polyolefin (A) that has an acidic group and/or an acid anhydride group and is soluble in the organic solvent, and an isocyanate compound, wherein the isocyanate compound comprises (B) a diisocyanate compound having a C4-7 hydrocarbon group and/or a derivative thereof, and (C) a diisocyanate compound having a C8-14 hydrocarbon group and/or a derivative thereof; and a heat-fusible member using the adhesive composition is also provided.

Adhesive composition and heat-fusible member using same

A molding packaging material excellent in interlaminar lamination strength is provided, in which it is possible to prevent deterioration of the interlaminar strength due to influences of electrolytes and also possible to prevent deterioration of the interlaminar strength due to influences of heat generation and/or expansion/contraction of the packaging material caused by repetition of charging/discharging. The molding packaging material of the present invention includes a heat resistant resin layeras an outer layer, a polypropylene layeras an inner layer, a metal foil layerarranged between the heat resistant resin layer and the polypropylene layer, wherein at least an inner side surface of the metal foil layeris subjected to a chemical conversion treatment, and the polypropylene layeris laminated on the chemical conversion treatment surface of the metal foil layer via an adhesive layer, wherein the adhesive layeris formed by applying an adhesive to the chemical conversion treatment surface of the inner side surface of the metal foil layer, the adhesive containing at least an organic solvent, a polyolefin resin having a carboxyl group in which the organic solvent is dissolved and an MFR measured at 130&#xb0; C. is 5 g/10 min to 42 g/10 min, and a multifunctional isocyanate compound.

Molding packaging material and method for producing same

Provided is an adhesive composition leading to sufficient adhesive strength when used for bonding to a polyolefin resin molded article that bonds poorly with other members. Also provided is an adhesive composition having excellent heat resistance (heat resistant adhesion) in the bonded part of a composite body obtained by joining a polyolefin resin-formed body and other member. This adhesive composition contains an organic solvent, a carboxyl group-containing polyolefin resin which is dissolved in this organic solvent and which has a melt flow rate of 5 to 40 g/10 min when measured at 130&#xb0; C., and a polyfunctional isocyanate compound. This adhesive composition may further contain a carboxyl group-containing polyolefin resin having a melting point of 120&#xb0; C. to 170&#xb0; C.
