Document Type and Number:
Japanese Patent JP5802330
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide polyurethane resin forming compositions which are for use in sealing a membrane module and exhibit excellent curability and castability and low turbidity and which can ensure excellent flatness of a cut section when used as a sealing material for a membrane module and which can form a polyurethane resin that is less susceptible to elution. The present invention provides two polyurethane resin forming compositions which are for use in sealing a membrane module, namely, a polyurethane resin forming composition which comprises a chief material that contains (A) an organic polyisocyanate component and a curing agent that contains (B) a polyol component and which is characterized in that the chief material and/or the curing agent contains (C) a bicyclic amidinium salt represented by general formula (1), and a polyurethane resin forming composition which is characterized by comprising a chief material that comprises (A) an organic polyisocyanate component, a curing agent that comprises (B) a polyol component, and (C) a bicyclic amidinium salt represented by general formula (1).
