ABSTRACT:
Thermosetting elastomeric coating compositions are disclosed. The resinous binder of the coating compositions is based on a hard polyester polyol containing cycloaliphatic moieties plasticized with a soft polyurethane polyol and cured with a curing agent capable of reacting with active hydrogens, for example, an aminoplast curing agent. The coating compositions are particularly useful on elastomeric substrates such as high density polyurethane foams, as well as on metal substrates such as steel and aluminum.
