Title:
POLYURETHANE-RESIN-FORMING COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2017/006650
Kind Code:
A1
Abstract:
Provided is a polyurethane-resin-forming composition that has a combination of reactivity suitable for workability, minimal discoloration when irradiated with γ-rays for sterilization, reduced eluates, and minimal blockages when used as a banding member of a hollow-fiber membrane. A polyurethane-resin-forming composition (X) includes a main agent (I) that contains an isocyanate component (A) and a curing agent (II) that contains a polyol component (B), in which: the isocyanate component (A) contains diphenylmethane diisocyanate (MDI) or the like; the polyol component (B) contains a castor-oil-based polyol (B1), one or more (B2) selected from the group consisting of polyoxyethylene-polyoxypropylene aliphatic polyamines and polyoxyethylene aliphatic polyamines, and a polyoxypropylene aliphatic polyamine (B3); and the content ratio of (B2) and (B3) is (B2)/(B3)=50/50 to 3/97 (mass ratio).
