Abstract
A two-component solventless polyurethane adhesive composition including (A) at least one isocyanate component and (B) at least one polyol component. The isocyanate component (A) comprises an isocyanate prepolymer that is the reaction product of (Ai) a polyisocyanate and (Aii) an isocyanate-reactive component; wherein the isocyanate-reactive component comprises (Aiia) at least one polyol having a functionality greater than two, (Aiib) at least one aromatic polyester polyol having a functionality of greater than two, and (Aiic) at least one hydrophobic polyol. The polyol component (B) comprises (Bi) at least one polyether polyol having a functionality greater than two, (Bii) at least one aromatic polyester polyol transesterified with a natural oil, and (Biii) at least one phosphate ester polyol. A method for forming a laminate is also disclosed, the method comprising the steps of: (I) mixing the above reactants (components (A) and (B)) to form a solventless adhesive composition, (II) applying a layer of the solventless adhesive composition to a surface of a first substrate, (III) bringing the layer of the solventless adhesive composition on the first substrate into contact with a surface of a second substrate to form a laminate, and (IV) curing the solventless adhesive composition. A laminate comprising the above solventless adhesive composition is also disclosed.
