ABSTRACT:
Cured coatings having a high degree of extensibility and other desirable properties are obtained from compositions comprising a hydroxyl-containing, urethane reaction product containing a polyester component and an amine-aldehyde resin. Preferred compositions contain a polymeric polyol of low glass transition temperature. These compositions are storage-stable in one package, and the cured coatings are adherent, durable and highly extensible. These coatings are particularly useful on resilient and rubbery substrates, such as form rubber, polyurethane foam and vinyl foam, and on soft metal surfaces such as mild steel and aluminum.
