A two-component solventless polyurethane adhesive composition comprising an isocyanate component and an isocyanate-reactive component is disclosed, the composition comprising: an isocyanate component including an isocyanate-terminated prepolymer; and including the following: Isocyanate-reactive components: polyether polyols, phosphate ester adhesion promoters, and bio-based polyols. A method for forming a layered structure is also disclosed, the method comprising: by mixing an isocyanate adhesive component including an isocyanate-terminated prepolymer with a polyether polyol, a phosphate ester adhesion promoter, and a bio-based multicomponent An isocyanate-reactive adhesive component of an alcohol to form an adhesive composition; applying the adhesive composition to a surface of a first substrate; and placing a surface of a second substrate and the surface of the first substrate The adhesive composition is contacted to form the layered structure. Also revealed layered structure. |
