Abstract
A method for preparing a polyurethane wherein the components thereof have a long shelf life. The formulation is made by separately preparing a prepolymer solution, a crosslinking solution, and a cement solution. Upon utilization, the solutions are mixed together and applied. The urethane has very good fuel resistance and can be used as a coating in fuel tanks as well as to form integral fuel tanks.
