In a stainless steel flask equipped with an agitator, 45.6 grams of water were added, the agitator was turned on, then 25 grams of adipic acid dihydrazide were added. The mixture was agitated for at least 10 minutes until a stable dispersion was formed. 16.4 grams of 2-propanone were then added under mixing. A clear solution formed after a few minutes. Mixing was continued for at least another hour until reaction product precipitated and formed a stable dispersion. The temperature of the dispersion was allowed to drop to 105° F. or below, and 10 grams of an acrylic latex containing 51% of methacrylate and butyl acrylic polymer were added, followed by 3.0 grams of AQUAFLOW NLS-200. The Stormer viscosity of the dispersion was 105 Kreb units at 77° F.
