Abstract
Official abstract text for this publication.
An aqueous coating compositions including a coalescent represented by Formula I: R1—O—(A)n—R2, where R1 is hydrogen, a C1-C12 linear aliphatic, or a C1-C12 branchedaliphatic, A is an alkylene oxide, R2 is a hydrogen group, a C1-C4 linear aliphatic or branched aliphatic group, a C1-C4 linear or branched carbonyl group, or a benzyl group, and n has an average value from 3 to 25.
First claim
Opening claim text (preview).
What is claimed is: 1. An aqueous coating composition comprising: a binder; a coalescent represented by Formula I: R 1 —O—(A) n —R 2 , where R 1 is a C 1 -C 12 linear aliphatic, or a C 1 -C 12 branched aliphatic, A is an alkylene oxide, R 2 is a hydrogen group, or a C 1 -C 4 linear aliphatic or branched aliphatic group, and n has an average value from 7 to 25; and water. 2. The aqueous coating composition of claim 1 , wherein A is a homopolymer comprising monomeric structural units derived from propylene oxide or butylene oxide. 3. The aqueous coating composition of claim 1 , wherein A is a copolymer comprising monomeric structural units derived from propylene oxide and butylene oxide. 4. The aqueous coating composition of claim 1 , wherein the coalescent has a number average molecular weight from 300 to 1800 g/mol. 5. The aqueous coating composition of claim 1 , wherein the aqueous coating composition includes 5 to 65 weight percent binder solids based upon a total weight of the aqueous coating composition. 6. The aqueous coating composition of claim 5 , wherein the aqueous coating composition includes 0.5 to 15 weight percent of the coalescent represented by Formula I based upon a total weight of the coalescent and the binder solids. 7. The aqueous coating composition of claim 1 , wherein the aqueous coating composition further includes a freeze-thaw stabilizer, wherein the freeze-thaw stabilizer is from 0.1 to 15 weight percent of the aqueous coating composition based upon a total weight of the aqueous coating composition. 8. A coating formed from the aqueous coating composition of claim 1 .
