Polyisocyanate solution, as well as adhesives and paints using this

摘要

PPROBLEM TO BE SOLVED: To provide a polyisocyanate solution having excellent solvent solubility, compatibility with other resins and curability, and exhibiting suitable hardness, adhesivity, close contact, etc., when used as an adhesive or a coating material. PSOLUTION: This polyisocyanate solution is constituted by including an isocyanate group-terminated urethane prepolymer (A) obtained by reacting an organic polyisocyanate (A1) with a polyol (A2) comprising 20-40 mol% diol (A2-1) having an alcoholic hydroxy group and 80-60 mol% triol (A2-2) having an alcoholic hydroxy group and an organic solvent (B), wherein part of the triol (A2-2) is glycerol and 15-35 mol% of the polyol (A2) is glycerol.
