Abstract
Water emulsifiable ketoxime blocked polyol prepolymers which can be further mixed with a low melting diamine or diol curative and water to make a very low viscosity storage stable, castable, reactive mixture. The water and volatile ketoxime are driven off to form a polyurethane with excellent physical properties.
