ABSTRACT:
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.
