Abstract
A one-part moisture curable polyurethane adhesive composition comprises a blend of polyurethane prepolymers and one or more additives which unexpectedly improve the sag resistance and mechanical properties of the formulation. The final adhesive composition retains good stability in the absence of moisture for an extended period between manufacture and application of the adhesive, and has a relatively rapid and consistent cure rate in the presence of atmospheric moisture. The final cured composition exhibits good mechanical properties and generally is unaffected by ambient application and cure conditions.
