Abstract:
PROBLEM TO BE SOLVED: To provide a curable epoxy resin composition excellent in curability, storage stability and also adhesiveness, and usable as a one-liquid type composition. SOLUTION: The curable epoxy resin composition comprises (A) an epoxy resin compound expressed by formula (I), and (B) a modified amine-based curing agent selected from (b) and (b'), wherein (b) is a modified amine-based curing agent which is an adduct formed by reacting a polyamine compound having at least one active hydrogen with an epoxy compound, or that formed by further reacting the adduct with a compound having at least two acidic hydroxy groups, and (b') is a modified amine based curing agent prepared by reacting a chain polyamine compound having at least two NH 2 groups with a polyisocianate.

Abstract:
PROBLEM TO BE SOLVED: To provide an epoxy resin composition excellent in adhesion to polyimide; and an insulating adhesive for polyimide having excellent adhesion to polyimide and also having excellent insulating properties and moisture resistance.SOLUTION: This epoxy resin composition includes: an epoxy resin (A); a rubber component (B) principally consisting of a maleic anhydride-modified hydrogenated styrene butadiene rubber; a polyphenylene ether (C); and at least one phosphorus compound (D) selected among from inorganic metal salts of phosphorus compounds and complexes thereof. An insulating adhesive for polyimide containing the epoxy resin composition is also provided. In the epoxy resin composition: 10-30 mass% of the component (A), 30-50 mass% of the component (B), and 30-50 mass% of the component (C) are included relative to the total amount of the components (A), (B) and (C); while 10-20 pts.mass of the component (D) is included based on 100 pts.mass of the total amount of the components (A), (B) and (C).
Abstract:
PROBLEM TO BE SOLVED: To provide an epoxy resin composition for low-elastic thermosetting resin, wherein the resin composition is used as an insulating adhesive having high glass transition temperature (Tg) and is excellent in features such as low elasticity (stress-relieving properties) and low coefficient of thermal expansion; and to provide the insulating adhesive suitably used for electric components.SOLUTION: The epoxy resin composition is obtained by containing an epoxy resin (A), a core-shell type low-elastic filler (B), and a polyamide resin (C). The thermosetting insulating adhesive contains the resin composition. The content of the polyamide resin (C) is 50-150 pts.mass based on 100 pts.mass of the epoxy resin (A); and the content of the core-shell type low-elastic filler (B) is 20-50 mass% of all formulations.
