摘要 |
<p>A moisture-curable polyurethane formulation is provided capable of curing to form a reaction product, having high green strength and being dispensable from a caulking gun. The polyurethane formulation comprises at least one isocyanate-terminated prepolymer, at least one rheology modifier or filler, optionally monomeric/polymeric isocyanate, and at least one urea-based thixotropic additive added to the formulation or formed in situ,to provide greater than 1% of urea groups in the reaction product.A method for making a moisture-curable polyurethane formulation capable of curing to form a reaction product and methods of bonding materials together using the formulation are also provided.</p> |
