Abstract:
A two-component solventless adhesive composition is disclosed, the adhesive composition comprising an isocyanate component comprising at least one isocyanate, and a polyol component comprising at least one amine-initiated polyol having a functionality of from 3 to 8 and a hydroxyl number of from 20 to 1,000. Further, a method for forming a laminate is disclosed, the method comprising forming a solventless adhesive composition comprising an amine-initiated polyol, applying a layer of the adhesive composition to a surface of a film, bringing the layer into contact with a surface of another film to form a laminate, and curing the adhesive composition. Still further, a laminate formed by the method is disclosed.
