ABSTRACT:
Water-borne and solvent-borne storage stable polyurethane coatings having improved flexibility and solvent resistance are obtained from a hydroxyl-containing polyester based on dimer acid and a diisocyanate resin. These compositions are storage stable and when cured with an amine aldehyde resin form very durable and highly extensible coatings. These compositions are especially useful in paint compositions wherein the paint compositions are applied to extensible, resilient, rubbery substrates and metal substrates.
