    摘要: A water-based silylated urethane composition is used as a water-based adhesive that has high safety, develops satisfactory tackiness in a short time and has excellent initial bond strength. The water-based silylated urethane composition contains following Components (A), (B) and (C): (A) a urethane prepolymer containing an anionic group and a tertiary amino group and having a terminal alkoxysilyl group, the urethane prepolymer (A) being a reaction product of an anionic-group-free polyol compound (A1), an anionic-group-containing polyol compound (A2), a compound (A3) containing a tertiary amino group and an isocyanate-reactive group, a polyisocyanate compound (A4), an alkoxysilane compound (A5) containing an isocyanate-reactive group, and an amine-based chain extender (A6); (B) a basic compound; and (C) water
