Abstract
Compositions for bonding substrate surfaces, particularly steel, aluminum, and urethane-primed galvanized steel, are disclosed. Desirably, the compositions include a stable emulsion including: (a) at least one curable (meth)acrylate component; (b) at least three different elastomeric polymers that are soluble and/or partially soluble in the (meth)acrylate component; and (c) optionally at least one elastomeric polymer that is not soluble in the (meth)acrylate component. Methods for preparing and methods for using these compositions also are disclosed.
