반응 단계
22.4 g DP9C/012, 3.9 g Poly G 83-34, 1.0 g Pluronic L-62, 0.4 g trimethylolethane, 2.0 g Cirrasol G-265, 1.0 g DMAMP DBS, and 0.11 g tin catalyst are added to 2.6 g N-methyl pyrrolidone plus 4.7 g methylethylketone, 2.8 g tertiary amyl alcohol, 0.6 g 2,4-pentanedione and 4.0 g diacetone alcohol and are mixed together. The mixture is heated to 60° C. and then reacted for 6 hours in a nitrogen atmosphere. Following the reaction, the resulting polyurethane prepolymer mixture is cooled and then dispersed in 59.0 g of distilled water, 0.1 g trimethylolethane, and 0.2 g triethanolamine with a high shear disperser, resulting in a stable aqueous polyurethane dispersion having about 24% solids by weight of the dispersion. The resulting polyurethane comprises about 3% polyethylene oxide side chains by weight of the solids of the polyurethane, about 12% polyethylene oxide main chains by weight of the solids of the polyurethane, and about 48% blocked polyisocyanates by weight of the solids of the polyurethane.
