Claims
- 1. A curable, solid, one-component epoxy resin composition, which is stable on storage at room temperature, consisting essentially of
- (a) one or more crystalline, solid epoxy resin, said resin having on average more than one epoxide group in the molecule and a melting point between 40.degree. and 150.degree. C.;
- (b) 1 to 12% by weight, based on component (a), of a curing catalyst; and
- (c) 5 to 30% by weight, based on the total of components (a) and (b), of a thermoplastic polymer in powder form.
- 2. A composition according to claim 1 wherein the epoxy resin of component (a) has a melting point between 60.degree. and 100.degree. C.
- 3. A composition according to claim 1 wherein the epoxy resin of component (a) is selected from the group consisting of diglycidyl isophthalate, diglycidyl terephthalate and mixtures thereof.
- 4. A composition according to claim 1 wherein the epoxy resin of component (a) additionally contains a crystalline epoxide group-containing adduct of an acid aliphatic polyester and an epoxide resin.
- 5. A composition according to claim 1 wherein component (b) is present at the 2 to 8% by weight level based on component (a).
- 6. A composition according to claim 1 wherein component (c) is present at the 5 to 20% by weight level based on the total of components (a) and (b).
- 7. A composition according to claim 1 wherein the thermoplastic polymer of component (c) is selected from the group consisting of ABS resins, ethylene/acrylic acid copolymers, ethylene/acrylate copolymers and ethylene/acrylic acid/acrylate copolymers.
