WIPO Patent Application WO/2023/042735
Kind Code:
A1
Abstract:
Provided is a two-pack curable adhesive agent having a rapid PAA reduction rate and excellent storage stability. The two-pack curable adhesive agent comprises: an isocyanate composition (X) which comprises a urethane prepolymer that is a reaction product of an isocyanate composition (i) having a 4,4'-MDI content of 75.0% by mass or more, a 2,2'-MDI content of 0.5% by mass or less and a 2,4'-MDI content of 5.0% by mass or less with a polyol composition (ii), a biuret derivative of 4,4'-MDI, and a urea derivative of 4,4'-MDI, in which the content of the biuret derivative is 0.4% by mass to 20.0% by mass inclusive and the content of the biuret derivative is 1.0 time or more larger than the content of the urea derivative; and a polyol composition (Y) which contains a polyol compound.
