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

Abstract

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 in this paper. Our approach has been to show the usefulness of prepared reactive nanogels as network precursors. It was shown that the application of nanogels did not affect the surface appearance and transparency of solvent-borne thermosetting coatings. Moreover, the presence of nanogel network precursors accelerated curing at ambient temperature and improved final hardness of coatings.
