Abstract

The present disclosure provides, in part, a solvent compound for use as a coalescent. More specifically, the present disclosure relates to VOC-exempt solvent compounds that may be used as coalescents and/or retarding solvents.

Claims (21)

1. A compound of Formula (I):

wherein R is C 1-12 alkyl, optionally substituted from one up to the maximum number of substituents with oxygen.

2. The compound of claim 1 , wherein the compound is:

3. The compound of claim 1 , wherein the compound is:

4. The compound of claim 1 , wherein the compound is a coalescent.

5. The compound of claim 4 wherein the compound is an inert coalescent or a film forming coalescent.

6. The compound of claim 1 , wherein the compound is a retarding solvent.

7. The compound of claim 1 , wherein the compound is a substitute for an ester alcohol.

8. The compound of claim 1 , wherein the compound is a reactive intermediate in the formation of an ester derivative for a plasticizer.

9. The compound of claim 1 , wherein the compound is a component in a thickener.

10. The compound of claim 1 , wherein the compound is an inert ingredient in an insecticide, fungicide or rodenticide formulation.

11. A kit or commercial package comprising the compound of claim 1 , together with instructions for use.

12. A method of forming a coating on a substrate, the method comprising applying a compound of Formula (I):

wherein R is C 1-12 alkyl, optionally substituted from one up to the maximum number of substituents with oxygen, to the substrate.

13. The method of claim 12 , wherein the compound is:

14. The method of claim 12 , wherein the compound is:

15. The method of claim 12 , wherein the compound is provided in admixture with a paint.

16. The compound of claim 2 , wherein the compound is a coalescent.

17. The compound of claim 3 , wherein the compound is a coalescent.
