WIPO Patent Application WO/2020/179609
Kind Code:
A1
Abstract:
Provided is a two-component adhesive having excellent moldability, heat-resistance, and moist-heat resistance. This two-component adhesive comprises a polyol composition (A) and a polyisocyanate composition (B), the polyol composition (A) containing: a polyester polyol (A1) which has a glass transition temperature of -30 ˚C to 20 ˚C, and is a reaction product of a polyhydric alcohol (a2) and a polybasic acid (a1) at least 30 mol% of which is an aromatic ring-containing polybasic acid (a1'); and a polyester polyol (A2) which has a glass transition temperature of 50 ˚C to 110 ˚C, and is a reaction product of a polyhydric alcohol (a4) and a polybasic acid (a3) at least 45 mol% of which is an aromatic ring-containing polybasic acid (a3'), 51 mol% or more of the aromatic ring-containing polybasic acid (a3') being a terephthalic acid, wherein the solid content mass ratio between the polyester polyol (A1) and the polyester polyol (A2) is 97/3 to 35/65.
