Abstract:
1. A moisture-curable polyurethane formulation capable of curing to form a reaction product, and comprising: a) at least one isocyanate-terminated prepolymer which is the product of an isocyanate reactive compound and at least one monomeric/polymeric isocyanate, wherein sufficient monomeric/polymeric isocyanate is present to provide an excess of free isocyanate in the prepolymer and/or formulation, wherein the NCO/OH mole ratio of the prepolymer is within the range of about 5 to about 20; b) optionally, additional monomeric/polymeric isocyanate; c) at least one of: d) at least one rheology modifier or filler; wherein the formulation is capable of being dispensed from a caulking gun and has sufficient green strength to adhesively bond a first substrate weighing at least 500 grams to a second substrate without the need for any holding instrument, wherein a contact surface between the first substrate and the second substrate is at least 18 inch
