Low odour coating compositions and paints |
摘要 |
<p>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.</p> |
