Sprayable compositions containing metal oxides

Abstract

The present invention provides a composition comprising a high load of metal oxides that is phase stable and sprayable. It comprises a branched hydrophobically modified ethoxylated urethane copolymer and a hydrophobically modified alkali swellable emulsion copolymer comprising of one or more acrylate monomers and an ethoxylated associative comonomer.
