Document Type and Number:
WIPO Patent Application WO/2022/210246
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: an epoxy resin composition which, when a fiber-reinforced resin is molded, can reduce surface unevenness caused by a difference in temperature between a molding temperature (a curing temperature) and normal temperature and exhibits high surface quality and excellent weathering resistance; a cured epoxy resin product; and a coated fiber-reinforced resin molded article obtained using same. To achieve the foregoing, this epoxy resin composition contains at least: an epoxy resin (A) comprising one or more epoxy resins; a thiol group-containing curing agent; and a catalyst (C). An epoxy resin (A1), which accounts for 50% or more in terms of weight ratio of the epoxy resins that constitute the epoxy resin (A), has 2 or more epoxy groups having a glycidyl structure and 1 or more epoxy groups having an alicyclic structure.
