Abstract
A polyurethane, being the reaction product of a polyester or polyether polyol with 1.5 to 2.5 equivalents of polyisocyanate, 0.05 to 0.40 equivalents of water cured with a polyol having less than 800 molecular weight.
Claims2
A polyurethane comprising the reaction product of an equivalent of a reactive hydrogen containing material of 400 to 6000 molecular weight selected from polyester polyol or polyether polyol with a degassed reaction product of 1.5 to 2.5 equivalents of an organic polyisocyanate and 0.05 to 0.40 equivalents of water cured with about 0.90 to 1.00 equivalents of a polyol having less than 800 molecular weight.
