Disclosed is an orthopedic casting material comprising a fabric coated or impregnated with a blend of polyisocyanate prepolymer and an effective detackifying quantity of one or more hydrophilic bisurethanes. In a preferred embodiment, the hydrophilic bisurethane is derived from the reaction of a polyethylene glycol having a molecular weight of about 4000 and methylene-4,4'- bis(phenylisocyanate) to form an isocyanate-terminated prepolymer which is then reacted with ethanol.

Orthopedic casting material having reduced tack and reduced slip

An orthopedic casting material which is coated on a flexible material as a water-curable prepolymer resin wherein the resin is formed by the reaction of an isocyanate and a polyol where the polyol has a colorant premixed therein and an effective detackifying quantity of one or more hydrophilic bisurethanes is added thereto.
