Abstract
Two-component solventless polyurethane adhesive compositions are disclosed comprising an isocyanate component comprising an isocyanate, and a polyol component comprising an amine-initiated polyol comprising two or more primary hydroxyl groups and a backbone incorporating tertiary amines, wherein the amine-initiated polyol comprises a functionality of from 2 to 12, a hydroxyl number of from 5 to 1,830, and a viscosity at 40° C. of from 500 to 20,000 mPa-s, and a silicone-based additive (e.g., an anti-foaming agent and/or a wetting agent). The adhesive compositions are formulated such that the isocyanate and polyol components can be applied to separate substrates prior to mixing. Laminate structures comprising the disclosed adhesive compositions and further comprising a metal or metallized substrate are also disclosed.
