Claims
- 1. A formable coating composition comprising:
- (a) a phenoxy resin;
- (b) about 1 to about 50 percent by weight of the total resin of a modifier resin which is relatively soft in comparison to the phenoxy resin and has:
- (1) a reduced viscosity of about 0.1 to about 2 dL/g in tetrahydrofuran at 20.degree. C.;
- (2) a Tg of about -120.degree. to about 30.degree. C.;
- (3) a solubility in Cellosolve acetate at 25.degree. C. of at least about 1 g. per 100 g. of solvent; and
- (4) a molecular weight of about 2,000 to about 90,000;
- (c) a crosslinker; and
- (d) optionally, a particulate material.
- 2. A coating composition of claim 1 wherein the concentration of the modifier resin is about 5 to about 30% by weight.
- 3. A coating composition of claim 1 wherein the modifier resin has:
- (1) a reduced viscosity of about 0.2 to about 1 dL/g in tetrahydrofuran at 25.degree. C.; and
- (2) a Tg of about -100 to about 0.degree. C.
- 4. A coating composition of claim 1 wherein the modifier resin is a polyalkylene oxide.
- 5. A coating composition of claim 4 wherein the polyalkylene oxide is UCON 25H or UCON 75H.
- 6. A coating composition of claim 1 wherein the modifier resin is a polyester.
- 7. A coating composition of claim 6 wherein the modifier resin is an aliphatic polyester.
- 8. A coating composition of claim 7 wherein the aliphatic polyester is derived from epsilon-caprolactone.
- 9. A coating composition of claim 1 wherein the modifier resin is a polyester urethane.
- 10. A coating composition of claim 1 wherein the modifier resin is a polyether urethane.
- 11. A coating composition of any one of claims 1 or 3 wherein the particulate material is zinc pigment.
- 12. A corrosion-resistant article comprising a metallic substrate and adhering thereto a coating composition of any one of claim 1 or 3.
- 13. A coating composition of claim 1 containing a crosslinker which is a melamine resin.
- 14. An article comprising a drawn-redrawn metallic substrate and adhering thereto a coating composition of claim 1.
