Abstract

An architectural coating material comprising a) an aqueous dispersion of at least one polyacrylate and b) at least one branched, cyclic and/or acyclic C₉-C₁₆ alkane functionalized with at least two hydroxyl groups.

Claims

1. An architectural coating material comprising

a) an aqueous dispersion of at least one polyacrylate and

b) at least one C₉-C₁₆ alkane functionalized with at least two hydroxyl groups, said alkane being selected from the group consisting of branched alkanes, cyclic alkanes, acyclic alkanes, and mixtures thereof.

2. The architectural coating material of claim 1, wherein the functionalized alkane b) is liquid at room temperature.

3. The architectural coating material of claim 2, wherein the functionalized alkane b) has a boiling point of more than 200°

C.

4. The architectural coating material of claim 1, wherein the functionalized alkane b) is acyclic.

5. The architectural coating material of claim 1, wherein the functionalized alkane b) comprises hydroxyl groups selected from the group consisting of primary hydroxyl groups, secondary hydroxyl groups, and mixtures thereof.

6. The architectural coating material of claim 5, wherein the functionalized alkanes b) are selected from the group consisting of diols, triols, and mixtures thereof.

7. The architectural coating material of claim 6, wherein the functionalized alkanes b) are positionally isomeric dialkyloctanediols.

8. The architectural coating material of claim 7, wherein the functionalized alkanes b) comprise 2,4-diethyl-1,5-octanediol.

9. The architectural coating material of claim 1, wherein the functionalized alkanes b) are present therein in an amount of from 0.01 to 10% by weight, based on the overall amount of the architectural coating material of the invention.

10. The architectural coating material of claim 5, wherein the functionalized alkane b) comprises a mixture of primary and secondary hydroxyl groups.

11. The architectural coating material of claim 7, wherein the functionalized alkanes b) are positionally isomeric diethyloctanediols.

12. The architectural coating material of claim 8, wherein the functionalized alkanes b) consist of 2,4-diethyl-1,5-octanediol.

13. The architectural coating material of claim 9, wherein the functionalized alkanes b) are present therein in an amount of from 0.1 to 8% by weight, based on the overall amount of the architectural coating material of the invention.

14. The architectural coating material of claim 13, wherein the functionalized alkanes b) are present therein in an amount of from 0.5 to 5% by weight, based on the overall amount of the architectural coating material of the invention.

15. The architectural coating material of claim 14, wherein the functionalized alkanes b) are present therein in an amount of from 0.8 to 2% by weight, based on the overall amount of the architectural coating material of the invention.
