Abstract
Official abstract text for this publication.
Embodiments of the present invention relate to aqueous coating compositions and to methods for improving the freeze/thaw stability of aqueous coating compositions. In one aspect, an aqueous coating composition comprises an aqueous polymeric dispersion and a compound according to Formula (1) as described herein.
First claim
Opening claim text (preview).
We claim: 1. An aqueous coating composition comprising an aqueous polymeric dispersion and a compound according to Formula 1: wherein R 1 is hydrogen, R 2 is an alkyl group having 2 to 6 carbon atoms, R 3 is hydrogen, and R 4 is hydrogen, a linear, branched, or cyclic alkyl group having 1 to 8 carbon atoms, wherein the sum of the x values is an average value from 1 to 10, the sum of the y values is an average value ranging from 1 to 10, and z is 0, and x+y+z is from 3 to 20; and wherein the coating composition comprises 0.1 to 10 percent by weight of compounds according to Formula 1 based on the weight of the polymeric dispersion solids. 2. The coating composition of claim 1 , wherein the compound has a molecular weight from 500 to 6000. 3. The coating composition of claim 1 , further comprising at least one coalescent. 4. The coating composition of claim 1 , wherein the aqueous polymeric dispersion comprises an acrylic polymer. 5. The coating composition of claim 1 further comprising one or more binders. 6. A method for improving the freeze/thaw stability of an aqueous coating composition comprising an aqueous polymeric dispersion, the method comprising adding the compound of Formula 1 to the aqueous coating composition: wherein R 1 is hydrogen, R 2 is an alkyl group having 2 to 6 carbon atoms, R 3 is hydrogen, and R 4 is hydrogen, a linear, branched, or cyclic alkyl group having 1 to 8 carbon atoms, wherein the sum of the x values is an average value from 1 to 10, the sum of the y values is an average value ranging from 1 to 10, and z is 0, and x+y+z is from 3 to 20. 7. The method according to claim 6 , wherein 0.1 to 10 percent by weight of Formula 1 is added, based on the weight of the polymeric dispersion solids.
