摘要：
This invention provides low odor stable coating compositions, and methods of their production. The stable aqueous coating compositions and paints comprise one or more emulsion-polymerized addition polymer and one or more carboxylesterase enzyme having an ester hydrolysis activity in the composition of less than 0.03 micromole/minute, wherein the aqueous coating composition has a headspace volatile organic compound (VOC) content, as measured by headspace gas chromatography-mass spectrometry (GC-MS) at 33° C., of less than 10 ppm of the one or more organic carboxylester with a normal boiling point of less than 150° C. and more than 50 ppm of the one or more mono-alcohol with a formula molecular weight of less than 76.
