Abstract:
The present invention provides polyurethanes including a reaction product of components including: (a) about 1 equivalent of at least one polyisocyanate; (b) about 0.05 to about 0.9 equivalents of at least one branched polyol having 4 to 18 carbon atoms and at least 3 hydroxyl groups; and (c) about 0.1 to about 0.95 equivalents of at least one diol having 2 to 18 carbon atoms, wherein the reaction product components are essentially free of polyester polyol and polyether polyol and the reaction components are maintained at a temperature of at least about 100°C for at least about 10 minutes, compositions, coatings and articles made therefrom and methods of making the same.
