  New and improved storage stable, one package, heat-curable poly urea/urethane coating compositions are disclosed which comprise: (a) a mixture or prepolymer of (i) a poly aliphatic isocyanate compound of the formula: wherein R and R' are each, independently, hydrogen, alkyl or substituted alkyl and X is a bridging means selected from divalent aliphatic, cycloaliphatic, or aromatic groups, or a polymeric adduct of said aliphatic isocyanate compound possessing poly aliphatic isocyanate functionality; and (ii) an approximately stoichiometric amount of at least one monomeric or polymeric compound containing a plurality of isocyanate reactive hydrogens; and (b) a minor effective amount of a polymerization calalyst. The compositions cure when heated to above about 100°C to form coatings which exhibit good abrasion resistance, solvent resistance, weather resistance and good adhesion to a wide variety of substrates. The coating compositions are stable upon storage for several months and have useful coating lives in the presence of atmospheric moisture of up to several days. In a preferred embodiment the new and improved poly urea/urethane coating compositions comprises a prepolymer solution containing a prepolymer derived from a,a,a',a'-tetramethylxylyene diisocyanate and 9-amino-10-hydroxystearylamine having a solids content of from about 30% by weight to about 80% by weight and an isocyanate content of from about 2% by weight to about 10% by weight, based on the total weight of the solution, and a minor effective amount of a dibutyltin dilaurate catalyst.
