The diisocyanate may be an aromatic or cycloalkyl diisocyanate such as 1,1'methylenebis(4-isocyanatocyclohexane), isophorone diisocyanate or tetramethyl xylene diisocyanate. The 1,1'-methylenebis(4-isocyanatocyclohexane) is commercially available as Desmodur® W from Mobay Corporation.
The ingredients were reacted at 220° C., under a nitrogen stream to a acid number less than one, producing a polyol with an hydroxyl eq. wt. of 315.

The mixture was heated, with stirring and under a trickle of dry air, to 70° C. and held at 70° C. for four hours to react the NCO groups of ingredient 7 with the hydroxy groups of ingredients 3 and 4 to form the oligomer. Upon cooling to about 45° C., a solution of the following ingredients were charged with stirring:
The series of formulations in Table II was prepared and tested as in Example 1. All of the formulations except B and C were prepared using the same catalysts, inhibitor and procedure as in Example 1. B and C were made similarly except they were reacted for one hour at 70° C. prior to adding the water, then for six hours after the water was added.
