| 摘要 |
The present invention is directed to a method of reducing the volatile organic content of an air-drying coating by admixing an alkoxylated organic amine with the coating. An alkoxylated organic amine is prepared by exposing alkylene oxide to an organic amine with structure (a), wherein R1, R2, R3 are individually a hydrogen atom, a methyl group, an ethyl group, a propyl group, a butyl group, a straight chain or branched chain alkyl group or aryl group; a methanol group, an ethanol group, a propanol group, a butanol group, or a straight chain or branched chain alcohol group; or an aminomethane group, an aminoethane group, an aminopropane group, an aminobutane group, aminoalkane group or an aminoaryl group. The alkoxylated organic amines of the present invention include ethoxylated and propoxylated diethylaminoethanol, monoethanolamine, monoisopropanolamine, dimethylethanolamine, propanediamine, propylenediamine, diethylenetriamine and 2-amino-2-methyl-1-propanol. The air-drying coating can be an architectural coating. The air-drying coating can also be a latex architectural coating. The present invention is also directed to a composition of an air drying coating with reduced or low VOC. The reduced or low VOC air-drying coating of the present invention includes ethoxylated or propoxylated organic amines.
