摘要

A sealer or adhesive composition based on a polyoxyalkylene polymer having a silicon-containing hydrolyzable group, which has improved adhesion in a dried, cured state with a paint coating containing acrylic resins, acrylic-urethane resins, or urethane resins. The improvement involves the addition to such a sealer/adhesive composition of an alkylarylsulfonamide contained therein in an amount of least about 50 phr or more, by weight. The invention also pertains to a method applying and adhering a paint coating to such a sealer composition after it is dried.
