Embodiment 1

[0021] 20 parts by weight of pyromellitic dianhydride (manufactured and sold by Alfa Aesar), 1 part by weight of tin(II)2-ethylhexanoate (manufactured and sold by Alfa Aesar) ) and 0.1 parts by weight of 2-ethyl-4-methylimidazole (2-ethyl-4-methylimidazole) (with a product number of EMI-24, manufactured and sold by T.C.I) into a reaction bottle, and Tetrahydrofuran (THF) was added as a solvent. Then, after sufficient stirring, 100 parts by weight of epoxy resin (diglycidylether of bisphenol A) (having a product number of DER 383, manufactured and sold by Dow Chemical Company) was added to the in the reaction vial. After sufficient stirring, resin composition (I) was obtained. The resin composition (I) is formed into a coating and the coating is subjected to a heat treatment, wherein the process temperature of the heat treatment is 100°C. The coating formed from the resin composition (I) was completely cured within 40 minutes to obtain a cured product. Next, the thermal dec...

Abstract

A curable resin composition, an article, and a method for fabricating the same are provided. The curable resin composition includes an epoxy resin; an anhydride; and a catalyst. In particular, the catalyst includes an imidazole and an organic metal compound, and the organic metal compound includes an organic tin compound, organic zinc compound, organic nickel compound, organic cobalt compound, organic copper compound, organic chromium compound, or a combination thereof.

Description

technical field [0001] The present invention relates to a hardenable resin composition, a cured shaped product, and a manufacturing method thereof, and particularly relates to a curable epoxy resin composition, a cured shaped product, and a manufacturing method thereof. Background technique [0002] Epoxy resin has been used on copper foil substrates and printed circuit boards for many years. The main reason is that epoxy resin has strong bonding strength with reinforcing materials (such as glass fiber cloth, etc.), and it will not volatilize when hardened. The composition and size are stable, and there will be no molding shrinkage. In addition, due to its excellent adhesion, mechanical strength, and electrical insulation properties, epoxy resins are also widely used in the fields of electronics and optics as coatings, adhesives, composite materials, or functional films. [0003] However, due to poor toughness and low thermal cracking temperature, existing epoxy resins have...
