Abstract:
The polyurethane resin composition comprises a main agent (I) which comprises an urethane prepolymer (A) with an isocyanate group terminal and a hardener (II) which comprises an urethane prepolymer (B) with a hydroxyl group terminal, wherein the urethane prepolymer (B) with the hydroxyl group is a product of reaction between a polyol ingredient (a) comprising a castor oil-based polyol (a1) and a polyisocyanate (b) can inhibit the hollow fiber membranes from clogging, regardless of the kind thereof, when the composition is used as a binder for hollow fiber membranes.
