<p>Disclosed are methods for imparting improved hydrolytic stability to a coating, adhesive, elastomer and/or sealant (CASE). The methods involve the addition of a phthalic anhydride derived polyester polyol. Also disclosed are non-foam hydrolytically stable urethane and pre-urethane compositions useful in the preparation of CASE materials, with improved hydrolytic stability.</p> |
