Abstract

A fluorine containing polymer which acts as a wetting, flow or leveling agent, and has at least one polar group. The polymer has at least one pendant or ether side chain containing from about 1 to about 20 carbon atoms with at least 25% of the hydrogen atoms being replaced by fluorine atoms. The fluorinated polymers unexpectedly impart wetting, flow or leveling properties to a variety of coatings while producing little foam.
