Abstract
Official abstract text for this publication.
Methods for abating airborne pollutants include applying a coating composition ath includes a an aqueous carrier, a binder, a pigment, and a formaldehyde scrubbing urea compound and curing the coating composition. The coated substrate absorbs formaldehyde and other air pollutants from passing air.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of abating airborne pollutants comprising applying to a substrate an aqueous coating composition that includes at least aqueous carrier liquid, a polymeric binder, one or more additives, and a formaldehyde scrubbing urea compound present in an amount of at most 1.5 weight percent based on the weight of the coating composition; and curing the coating composition. 2. The method of claim 1 , wherein the aqueous coating composition is applied to the substrate by roller. 3. The method of claim 1 , wherein the aqueous coating composition is applied to the substrate by brush. 4. The method of claim 1 , wherein the aqueous coating composition is applied to the substrate by sprayer. 5. The method of claim 1 , wherein the urea compound is present in the aqueous coating composition in an amount of at least 0.2 weight percent based on the weight of the aqueous coating composition. 6. The method of claim 5 , wherein the urea compound is present in an amount of at least 0.5 weight percent based on the weight of the aqueous coating composition. 7. The method of claim 1 , wherein the urea compound is present in the coating composition in an amount of at most 1.0 weight percent based on the weight of the aqueous coating composition. 8. The method of claim 1 , wherein the coating further includes a pigment. 9. The method of claim 1 , wherein the coating composition has a VOC of less than 150 g/L. 10. The method of claim 9 , wherein the coating composition has a VOC of less than 100 g/L. 11. The method of claim 10 , wherein the coating composition has a VOC of less than 50 g/L. 12. The method of claim 11 , wherein the coating composition is free of VOCs. 13. The method of claim 1 , wherein composition further includes a coalescent, a rheology modifier, a filler, an extender, a biocide, or a UV stabilizer. 14. The method of claim 1 , wherein the substrate is drywall. 15. The method of claim 1 , wherein the substrate is wood. 16. The method of claim 1 , wherein the substrate is brick. 17. The method of claim 1 , wherein the substrate is cement. 18. The method of claim 1 , wherein the substrate is an interior wall.
