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, wherein the first and second components are formulated to be applied to separate substrates before being brought together. Further, a method for forming a laminate is disclosed, the method comprising uniformly applying the isocyanate component to a first substrate, uniformly applying the polyol component to a second substrate, bringing the first and second substrates together, thereby mixing and reacting the isocyanate component and the polyol component to form an adhesive between the first and second substrates, and curing the adhesive to bond the first and second substrates. Still further, a laminate formed by the method is disclosed.
