Abstract
Official abstract text for this publication.
The invention relates to a coating composition comprising: (a) 10% to 99.9% by weight of resin based on the total weight of the coating composition; and (b) 0.1% to 20% by weight of a formaldehyde scavenger based on the total weight of the coating composition, wherein the formaldehyde scavenger has at least one active methylene hydrogen and is solid at room temperature. The invention relates to use of a coating composition for removing free formaldehyde from the environment, wherein the formaldehyde scavenger has at least one active methylene hydrogen and is solid at room temperature.
First claim
Opening claim text (preview).
The invention claimed is: 1. A coating composition, comprising: (a) 10% to 99.9% by weight of a resin based on the total weight of the coating composition; and (b) 0.1% to 20% by weight of a formaldehyde scavenger based on the total weight of the coating composition, wherein the formaldehyde scavenger has at least one active methylene hydrogen and is solid at room temperature, wherein: the resin is selected from the group consisting of poly(meth)acrylate, polyurethane, polysiloxane, alkyd, hybrid of poly(meth)acrylate and polyurethane, hybrid of inorganic-polyacrylate and any combination thereof; and the formaldehyde scavenger is selected from the group consisting of acetoacetamide, acetoacetanilide, potassium N-(acetoacetyl) sulfanilate, diacetoacet-2,5-dimethyl-1,4-phenylenediamide, diacetoacet-1,4-phenylenediamide, and any combination thereof. 2. The composition according to claim 1 , wherein the formaldehyde scavenger has a boiling point of no less than 50° C. 3. The composition according to claim 1 , wherein the formaldehyde scavenger is selected from the group consisting of acetoacetanilide, potassium N-(acetoacetyl) sulfanilate, diacetoacet-2,5-dimethyl-1,4-phenylenediamide, diacetoacet-1,4-phenylenediamide, and any combination thereof. 4. The composition according to claim 1 , wherein the resin is selected from the group consisting of a polyurethane, a polysiloxane, an alkyd, a hybrid of a poly(meth)acrylate and a polyurethane, a hybrid of an inorganic-polyacrylate, and any combination thereof. 5. The composition according to claim 1 , wherein the coating composition comprises 15% to 80% by weight of the resin based on the total weight of the coating composition. 6. The composition according to claim 1 , wherein the coating composition comprises 0.5% to 10% by weight of the formaldehyde scavenger based on the total weight of the coating composition. 7. The composition according to claim 1 , wherein the coating composition further comprises an additive selected from the group consisting of an antioxidant, a pigment, a thickener, a defoamer, a levelling agent, a coalescence agent, a dispersant, a surfactant, a biocide, and any combination thereof. 8. A removal method, comprising: removing free formaldehyde from the environment with the composition according to claim 1 , wherein the formaldehyde scavenger has at least one active methylene hydrogen and is solid at room temperature. 9. The method according to claim 8 , wherein the formaldehyde scavenger has a boiling point of no less than 50° C. 10. The method according to claim 8 , wherein the formaldehyde scavenger is selected from the group consisting of acetoacetamide, acetoacetanilide, potassium N-(acetoacetyl) sulfanilate, diacetoacet-2,5-dimethyl-1,4-phenylenediamide, diacetoacet-1,4-phenylenediamide, and any combination thereof.
