Abstract
The present invention relates to an epoxy resin composition containing an alicyclic epoxy compound (A), a polymer polyol having two or more terminal hydroxyl groups (B), and a Lewis acid-amine complex (C). The present invention provides an epoxy resin composition which can be cured by heating at low temperatures, and suppresses heat generation associated with curing (heat generation by curing). It is preferable that the epoxy resin composition further contains an antioxidant. Furthermore, it is preferable that the antioxidant is a phosphite ester compound.
Claims14
An epoxy resin composition comprising:
- an alicyclic epoxy compound (A);
- a polymer polyol having two or more terminal hydroxyl groups (B);
- a Lewis acid-amine complex (C);
- and
- an antioxidant, wherein the antioxidant is a phosphite ester compound,
- wherein the polymer polyol (B) is at least one selected from the group consisting of a polyester polyol, a polycarbonate polyol, a polyacryl polyol, an epoxy polyol, a polyolefin polyol and a polyether ester polyol,
- the Lewis acid-amine complex (C) being a complex comprising a Lewis acid and at least one amine compound selected from the group consisting of a primary amine and a secondary amine, and
- the content of the polymer polyol (B) being 50 to 2000 parts by weight based on 100 parts by weight of the Lewis acid-amine complex (C).
