The present invention relates to a process for producing a supporting bandage for surgical or veterinary surgical use comprising covering the part of the body which is required to be supported with an air-permeable dressing and then applying a self-hardening bandage over this dressing, characterized in that the self-hardening bandage comprise strips of air-permeable, flexible fabric coated and/or impregnated with about 50 to 300% by weight, based on the uncoated fabric, of an isocyanate prepolymer which contains free isocyanate groups and is based on aromatic polyisocyanates and polyols containing tertiary amino nitrogen atoms, the prepolymer having an isocyanate content of about 5 to 30% by weight and a tertiary amino nitrogen content of about 0.05 to 2.5% by weight, the coated fabric being soaked with water immediately before it is applied. The present invention also relates to lengths of bandaging material which comprise pieces of flexible, air-permeable fabric coated with about 50 to 300% by weight, based on the uncoated fabric, of an isocyanate prepolymer based on aromatic polyisocyanates and polyols containing tertiary amino nitrogen atoms, the isocyanate prepolymer having an isocyanate group content of about 5 to 30% by weight and a tertiary amino nitrogen content of about 0.05 to 2.5% by weight. |
