Abstract:
The present invention provides a circuit connecting material for electrically connecting a first circuit member having a first circuit electrode formed on a major surface of a first circuit substrate, and a second circuit member having a second circuit electrode formed on a major surface of a second circuit substrate, with the first and the second circuit electrodes opposed to each other, comprising an adhesive component containing a fluorine-containing organic compound, wherein the adhesive component contains 0.10% or less by mass of a silicon-containing compound, in terms of silicon atoms, based on the total amount of the adhesive component.
Abstract:
An acrylic rubber-metal composite, which comprises an iron phosphate treated iron-based metal, and an adhesive layer comprising a phenol resin and a metal oxide, and preferably further a halogenated polymer, and an acrylic rubber layer, successively provided on the iron-based metal surface, has not only distinguished initial adhesiveness and water resistance, when the acrylic rubber is bonded to the metal owing to application of the iron phosphate treatment to the metal surface, but also can reduce the abrasion of the mating materials when brought into contact with rubber-unbaked parts of the sheet, because the surface roughness Ra[according to JIS 0601(1994)] of the surface treated steel sheet is 0.6 or less.

PROBLEM TO BE SOLVED: To provide: a circuit connecting material that exhibits sufficiently good adhesive strength without depending on the material of a circuit member, and has sufficiently excellent transferability while a change in transferability over time is suppressed; a connection structure of a circuit member, using the circuit connecting material; and a method for manufacturing a connection structure of a circuit member.SOLUTION: There is provided a circuit connecting material for electrically connecting a first circuit member which includes a first circuit electrode formed on a principal surface of a first circuit board, and a second circuit member which includes a second circuit electrode formed on a principal surface of a second circuit board, in such a manner that the first and second circuit electrodes face each other. The circuit connecting material contains an adhesive component containing a fluorine-containing organic compound, the fluorine-containing organic compound has a silicone structure, and the adhesive component contains 0.10 mass% or less of a silicon-containing compound in terms of silicon atoms, based on the total amount of the adhesive component.
Abstract:
PROBLEM TO BE SOLVED: To obtain an ultraviolet-curing type removable pressure bonding composition having stable removability and an ultraviolet-curing type removable pressure bonding composition that has no change in bond strength with time even at high temperature and high humidity and slight variation of bond strength of cured coating film even in variation of ultraviolet irradiation amount during curing and does not break a substrate coated with an adhesive in use, namely, in releasing, and exhibits stable removability. SOLUTION: The ultraviolet-curing type removable pressure bonding composition comprises at least one kind of an ultraviolet-curable component selected from an ultraviolet-curable monomer and oligomer containing an acryloyl group or a methacryloyl group, a (meth)acrylic copolymer having ≤20°C glass transition temperature, a photopolymerization initiator and at least one kind of a fluorine-containing compound selected from (1) a fluorine-containing polymerizable compound, (2) a fluorine-containing copolymer having a fluorine-containing segment and a fluorine-free segment and (3) a fluorine-containing surfactant.
