Acrylic coatings modification by reactive nanogels prepared by emulsion polymerisation: A study

Abstract

In this paper, the influence of hydroxyl-functionalised acrylic nanogels incorporated into solvent-borne and water-borne acrylic binder system on the properties of coating films is described. Our approach has been to show the usefulness of prepared reactive nanogels as network precursors. As found out, the application of nanogels did not affect the surface appearance and the transparency of solvent-borne thermosetting coatings. Moreover, the presence of nanogel network precursors accelerated the cure at ambient temperature, thus improving the final hardness of coatings.
