Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an aqueous solid adhesive excellent in application working property, settlement after pasting, adhesion property to various adherends, heat resistance and waterproof property, and capable of performing a contact adhesion. SOLUTION: This aqueous solid adhesive contains the following (A), (B), (C) and (D) components. (A) an anionic group-containing polymer having an alkoxysilyl group terminal obtained by performing a reaction of (A1) a compound not containing the anionic group and containing multiple isocyanate- reactive groups, (A2) a compound containing the anionic group and multiple isocyanate-reactive groups, (A3) a polyisocyanate compound and (A4) an isocyanate-reactive group-containing alkoxysilane compound, (B) a basic compound, (C) water and (D) a gelling agent. |
