Preparation of polyurethane dispersion formulation

Polyurethane dispersions are being used increasingly in industrial applications. Because of the high cost of these dispersions they are being employed where the performance achieved with waterborne acrylic, alkyd, polyester and epoxy resins is not adequate, or they are being used in combination with other resins to improve certain properties. I will discuss the problems associated in formulating polyurethane dispersions, how these systems can be pigmented, and crosslinked with either melamine or polyisocyanate crosslinker and how to catalyze these formulations. In addition I plan to discuss how to combine these polyurethane dispersions with other polymer systems.
