An orthopedic casting material comprising a substrate impregnated with a water-curable resin comprising an aromatic polyisocyanate and a polyol, wherein the free NCO level of said prepolymer is from about 6% to about 10%. Preferably the free NCO level is from about 7% to about 8%. Preferably the polyol has a molecular weight of at least 2,000, and a hydroxyl number of from about 28 to about 56, preferably from about 35 to about 40. The casting material may be packaged as a kit with a casting aid comprising a substrate impregnated with a lubricating material.
