ADHESIVE COMPOSITION

摘要

The purpose of the present invention is to provide an adhesive composition having excellent storage stability and adhesion to a coated steel sheet. This adhesive composition includes: a mixture obtained by a method provided with a mixing step for mixing a liquid component (A) containing a polyol compound and a powder component (B) containing a filler to obtain a paste mixture, a dehydration step for removing at least a portion of moisture from the paste mixture after the mixing step, and a generation step for obtaining a mixture including a urethane prepolymer by mixing a polyisocyanate compound (C) and the dehydrated paste mixture and reacting component (C) and the polyol compound in the paste mixture; a bismuth-based compound and a tin-based compound as hardening catalysts; a CnH2n+1-COOH (n = 1-17) organic acid; and a polyisocyanate compound (D) having three or more isocyanate groups in one molecule thereof; the amount of the tin-based compound being 0.003-0.03 parts by mass per 100 parts by mass of the mixture.
