  • Polyurethane based adhesion composition and method
    Patent number: 5272224
    Abstract: A one-component, moisture-curable polyurethane-based adhesive composition useful for affixing glass panels directly to electrocoat painted metal substrates or over a primer 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.
    Type: Grant
    Filed: June 19, 1991
    Date of Patent: December 21, 1993
    Assignee: Adco Products, Inc.
