    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.
