<p><P>PROBLEM TO BE SOLVED: To provide a one-pack epoxy resin composition highly compatible in both stability in storage and curability, and its cured product. <P>SOLUTION: This one-pack epoxy resin composition contains epoxy resin that is in a liquid state at 25°C, a curing agent of acid anhydride base, and a curing catalyst. When the one-pack epoxy resin composition is stored for 14 days at 40°C and 60% RH, the bodying up magnification of viscosity at 25°C and 50 rpm measured by using an E type viscometer before and after the storage is 2.9 or less. The cured product is obtained by curing the one-pack epoxy resin composition by heating. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
