Abstract
Improved two component adhesives allowing the components to be mixed at essentially a 1:1 ratio, giving excellent sag resistance, low viscosity, excellent handling ability and satisfactory gel time, said adhesives being composed of a prepolymer composition and a curative composition that can be mixed preferably at 1:2 to 2:1 ratio and a curative composition composed of a mixture of a reaction product of a multiple hydroxyl polyol of relatively low equivalent weight with a small amount of an organic polyiisocyanate and a polyamine.
