Beschreibung
Zusammenfassung:	The present disclosure provides a two-component polyurethane adhesive composition and a bonding method thereof. The two-component polyurethane adhesive composition includes A) a polyol component, and B) an isocyanate component. The polyol component includes A1) one or more polyether polyols, and the isocyanate component includes B1) a first isocyanate prepolymer, wherein the first isocyanate prepolymer is polymerized from isocyanate and a non-linear chain extender. The two-component polyurethane adhesive composition of the present disclosure has good mechanical properties, in particular, high G modulus and high elongation. The polyol component in the two-component polyurethane adhesive composition has good phase stability, and good miscibility with the isocyanate component. The two-component polyurethane adhesive composition of the present disclosure can be used for the production and manufacture of mechanical parts such as automobile components.
