Accelerate cure polyurethane adhesive composition

A method of accelerating the cure of an adhesive composition comprising:

• a) providing a moisture curable adhesive composition comprised of
• A) an isocyanate terminated prepolymer and
• B) a cure accelerator comprised of
• i) an isocyanate reactive compound comprising:
• 1) a primary, secondary or tertiary amino group, or a primary thiol group and
• 2) an OH, NH, and/or SH functionality of 2 to 7 and
• ii) a polyol not having a primary, secondary or tertiary amino group, or a primary thiol group wherein the polyol is selected from a diol and/or triol;
• wherein the isocyanate terminated prepolymer and cure accelerator are separately provided;
• b) mixing the cure accelerator and the isocyanate terminated prepolymer to form an adhesive mixture;
• c) applying the adhesive mixture to at least a portion of a first substrate;
• d) contacting the substrate having the adhesive mixture thereon with a second substrate such that the adhesive mixture is therebetween;
• and
• e) allowing the adhesive mixture to cure bonding said substrates together.
