Abstract
An aqueous dispersion comprising at least one fatty acid-modified epoxy amine adduct wherein the fatty acid has an iodine number of lower than 30 and at least one polymer obtained from the polymerization of one or more ethylenically unsaturated monomers and their use for forming coatings or binder agents, especially for decorative and protective coating applications on various substrates.
Claims17
An aqueous dispersion comprising:
- at least one fatty acid-modified epoxy amine adduct ZYWS containing amino groups which are at least partially protonated, wherein the fatty acid WS of the at least one fatty acid-modified epoxy amine adduct ZYWS is a fatty acid that contains at least 8 carbon atoms and has an iodine number according to DIN 53241-1:1995-05 of lower than 30, and the fatty acid WS of the at least one fatty acid-modified epoxy amine adduct ZYWS is bound to the epoxy amine adduct through a hydroxyl ester link, and
- at least one polymer V obtained from the polymerization of one or more ethylenically unsaturated monomers, said at least one polymer V being hydrophobic.
