<P>PROBLEM TO BE SOLVED: To provide a two-liquid normal temperature curable urethane coating film water-proof material composition excellent in a curing property and a construction-jointing property. <P>SOLUTION: The two-liquid normal temperature curable urethane coating film water-proof material composition has a first liquid containing a urethane prepolymer obtained by reacting a tolylene diisocyanate with a polyol, and a second liquid containing a fluorine group-containing (meth)acrylate, a diamine compound containing a toluenediamine structure and an acid catalyst. In the two-liquid normal temperature curable urethane coating film water-proof material composition and its laminated body, the ratio of the isocyanate group of the urethane prepolymer relative to the amino group of the diamine compound, i.e., the ratio of isocyanate group/an amino group is 0.8-5.0 in equivalent ratio. <P>COPYRIGHT: (C)2008,JPO&INPIT |
