摘要：The present invention provides polyurethanes including a reaction product of
components including: (a) an isocyanate functional urethane prepolymer comprising areaction product of components including: (i) about 1 equivalent of at least one
polyisocyanate; and (ii) about 0.1 to about 0.5 equivalents of at least one diol having 2 to18 carbon atoms; and (b) about 0.05 to about 0.9 equivalents of at least one branchedpolyol having 4 to 18 carbon atoms and at least 3 hydroxyl groups; and (c) up to about0.9 equivalents of at least one polyol different from branched polyol (b) and having 2 to18 carbon atoms, wherein the reaction product components are essentially free ofpolyester polyol and polyether polyol; compositions, coatings and articles madetherefrom and methods of making the same.
