Low odour coating compositions and paints

摘要

This invention provides low odour stable coating compositions, and methods of their production. The stable aqueous coating compositions and paints comprise one or more emulsion-polymerised 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.
