ABSTRACT:
A primerless, one-component, moisture-curable polyurethane-based adhesive composition useful for affixing glass panels directly to electrocoat painted metal substrates comprises a polyurethane base polymer containing an electrocoat adhesion promoter. The sealant composition has fast cure times at ambient temperatures and forms a strong bond directly to electrocoat painted metal substrates without the need for a sealant primer.
