Abstract:
The present invention provides: an adhesive composition comprising an isobutylene-based polymer (A), a diene-based rubber (B) that includes a hydroxyl group, and a crosslinking agent (C); an adhesive sheet comprising an adhesive layer that is formed using the adhesive composition; and an electronic device comprising a sealing material, the sealing material being formed using the adhesive composition, or the adhesive. According the present invention, provided are; an adhesive composition that is useful as a material for forming an adhesive layer that exhibits an excellent water barrier capability, and exhibits adhesion and holding power in a well-balanced manner; an adhesive sheet that includes an adhesive layer that is formed using the adhesive composition; and an electronic device that includes a sealing material that is formed using the adhesive composition.
Abstract:
The present invention is a sealing sheet comprising at least a base resin layer and a sealing resin layer, the base resin layer having a microstructure that is provided to one surface of the base resin layer, the sealing resin layer being provided on a side of the base resin layer on which the microstructure is provided, and the microstructure having a protrusion that has a maximum difference in height (H) of 1 to 50 μm and is arranged two-dimensionally on the surface of the base resin layer, and an electronic device member, and an electronic device. The sealing sheet according to the invention exhibits an excellent gas barrier capability that suppresses or reduces the entry of a gas (e.g., water vapor) not only in the vertical direction, but also in the horizontal direction (from the edge) with respect to the surface of the sealing sheet.
Abstract:
The present invention provides: an adhesive composition comprising a diene-based rubber (A) that includes a radiation-curable functional group, a cured adhesive layer having a thickness of 60 μm that is formed by curing the adhesive composition having a water vapor transmission rate at a temperature of 40° C. and a relative humidity of 90% of 30 g/(m2·day) or less; an adhesive sheet comprising a curable adhesive layer that is formed using the adhesive composition; and an electronic device comprising a sealing material, the sealing material being formed using the adhesive composition. According to the present invention, provided are: an adhesive composition that is useful as a material for forming an adhesive layer that exhibits an excellent water barrier capability and sufficient cohesive strength, and exhibits adhesion and holding power in a well-balanced manner, an adhesive sheet that includes an adhesive layer that is formed using the adhesive composition, and an electronic device that includes a sealing material that is formed using the adhesive composition.
