Abstract
The present invention pertains to nanoemulsions of alkyd in aqueous liquids and e.g. nanoemulsions prepared by emulsifying an alkyd mixture in an aqueous liquid, said alkyd mixture comprising an alkyd and an unsaturated hydroxy fatty acid. The invention furthermore pertains to methods of producing the nanoemulsion, and to uses of the nanoemulsion and/or the alkyd nano droplets contained therein.
Claims16
A nanoemulsion of nano droplets comprising alkyd, the nano droplets having an average hydrodynamic particle diameter of at most 350 nm and furthermore comprising a source of unsaturated hydroxy fatty acid (suhfa), said source comprises:
- i) a free, unsaturated hydroxy fatty acid (fuhfa),
- ii) a free oligoester of unsaturated hydroxy fatty acid (ouhfa) comprising di(unsaturated hydroxy fatty acid) (duhfa) and tri(unsaturated hydroxy fatty acid) (tuhfa), and/or
- iii) a free hydroxy carboxylic acid ester of i) or ii) wherein the hydroxy carboxylic acid has a molecular weight of at most 250 g/mol,
- wherein the weight ratio between the total amount of fuhfa+duhfa+tuhfa and the total amount of alkyd is in the range of 0.01-0.30.
