ABSTRACT:
Disclosed is dispersion of a polyurethane-urea polymer in a continuous phase. This dispersion contains about 0.1 to about 5 parts by weight of an ionizable, non-volatile salt per 100 parts by weight of polyurethane-urea polymer. Polyurethane-urea coatings made from this dispersion have excellent static dissipative properties.
