    Abstract: Thermosetting resins containing hydroxyl groups which can be cured with aminoplast resins are stabilized by the addition of 1,4-diazo[2,2,2]-bicyclooctane. This method is particularly useful in stabilizing the gloss retention of extensible coatings formed by curing a hydroxyl-containing urethane product with an aminoplast resin. Such coatings can be applied to virtually any solid substrate and are especially useful on rubbery, resilient substrates such as polyurethane or polyethylene foam, natural or synthetic rubber or rubber foam, and various elastomeric plastic materials. They are also particularly useful on other substrates such as mild steel or aluminum.

    Abstract: Cured coatings having a high degree of extensibility, gloss retention, good sprayability and other desirable properties are obtained from compositions comprising (A) an interpolymer of a hydroxyalkyl ester of an ethylenically-unsaturated carboxylic acid and a copolymerizable material; (B) an organic polyisocyanate; (C) a polymeric polyol of low glass transition temperature; and (D) a curing agent, present either externally and/or as a part of the interpolymer. These compositions, when used as coatings, are durable, adherent and highly extensible. The coatings are particularly useful on resilient and rubbery substrates such as EPDM rubber, foam rubber, polyurethane foam and vinyl foam and on soft metal surfaces such as steel and aluminum.
