Claims
- 1. A composition comprising:(a) a polycarbodiimide having at least two carbodiimide groups; (b) an aqueous emulsion polymer; and (c) an alkoxysilane; wherein said aqueous emulsion polymer has at least two functional groups reactive with said carbodiimide groups and at least one functional group reactive with said alkoxysilane; and wherein said alkoxysilane has at least one functional group reactive with said aqueous emulsion polymer.
- 2. The composition of claim 1,wherein said at least one functional group of said aqueous emulsion polymer is selected from the group consisting of carboxylic acid and amine.
- 3. The composition of claim 1,wherein said at least one functional group of said alkoxysilane is an epoxy.
- 4. The composition of claim 1,wherein said at least one functional group of said aqueous emulsion polymer is a 1,3-diacarbonyl.
- 5. The composition of claim 1,wherein said at least one functional group of said alkoxysilane is an amine.
- 6. A method for producing a wear-resistant coating on a surface of a substrate comprising:(1) applying to said surface a layer of coating composition comprising: (a) a polycarbodiimide having at least two carbodiimide groups; (b) an aqueous emulsion polymer; and (c) an alkoxysilane; wherein said aqueous emulsion polymer has at least two functional groups reactive with said carbodiimide groups and at least one functional group reactive with said alkoxysilane; and wherein said alkoxysilane has at least one functional group reactive with said aqueous emulsion polymer; and (2) allowing said coating composition to dry.
- 7. The method of claim 6,wherein said at least one functional group of said aqueous emulsion polymer is selected from the group consisting of carboxylic acid and amine.
- 8. The method of claim 6,wherein said at least one functional group of said alkoxysilane is an epoxy.
- 9. The method of claim 6,wherein said at least one functional group of said aqueous emulsion polymer is a 1,3-dicarbonyl.
- 10. The method of claim 6,wherein said at least one functional group of said alkoxysilane is an amine.
- 11. A method for producing a wear-resistant coating on a surface of a substrate comprising:(1) applying to said surface a layer of coating composition comprising: (a) a polycarbodiimide having at least two carbodiimide groups; (b) an aqueous emulsion polymer; and (c) an alkoxysilane; wherein said aqueous emulsion polymer has at least two functional groups reactive with said carbodiimide groups; and wherein said alkoxysilane has least one functional group reactive with said carbodiimide groups; and (2) allowing said aqueous coating composition to dry.
- 12. The method of claim 11,wherein said at least two functional groups of said aqueous emulsion polymer are acid functional.
- 13. The method of claim 11,wherein said at least one functional group of said alkoxysilane is selected from the group consisting of carboxylic acid and mercaptan.
- 14. A method for producing a wear-resistant traffic marking on a road surface comprising:(1) applying to said road surface a layer of a traffic marking composition comprising: (a) an aqueous emulsion polymer; and (b) a polycarbodiimide having at least two carbodiimide groups; wherein said aqueous emulsion polymer has at least two functional groups reactive with said carbodiimide groups; and wherein said polycarbodiimide has at least one alkoxysilane group; and (2) allowing said traffic marking composition to dry.
- 15. The method of claim 14,wherein said at least two functional groups of said aqueous emulsion polymer are acid functional.
