Abstract
1,221,840. Dip moulding polyurethane articles. TAKEDA YAKUHIN KOKYO K.K. 5 Aug., 1968 [7 Aug., 1967], No. 37328/68. Heading B5A. Polyurethane articles are moulded by dipping a mould into a first liquid, removing the mould from the first liquid dipping the mould into a second liquid and stripping the article from the mould, the dipping being carried out in any desired order and any desired number of times. Preferably the mould is dipped from 2 to 6 times in the polyurethane prepolymer and curing agent. The polyurethane prepolymers may be isocyanato-terminated, hydroxyl terminated or amino-terminated, many examples being driven, and are used in a 1 to 80 wt. per cent solution with a viscosity of 0À6-20 centipoise, the mould being raised at a speed between 200 and 1000 mm./min. The curing agent is preferably a polyamine used in a 0À01- 10 wt. per cent solution. After the final dipping the articles may be dried at room temperature on an elevated temperature of 40-120 C.
