Abstract

A coating composition that includes a polymer having (i) a barrier segment with aromatic groups and urethane linkages, urea linkages, or a combination thereof and (ii) an elastomeric segment that is different from (i). The barrier segment makes up at least 30 weight % of the polymer based on the total solids weight of the polymer. Further, the composition also includes an adhesion promoter having: (a) at least one epoxy functional polymer and a thiol functional crosslinker reactive with the epoxy functional polymer; and/or (b) a hydrazide functional component.
