A component to control the viscosity of phase change material formulations is made by reacting selected nucleophiles, including fatty acid/alcohol reactants with an isocyanate, is disclosed. The addition of the isocyanate and the different nucleophiles will create a viscosity modifying component of low viscosity that can be formulated with higher molecular weight polyamide resins to achieve increased toughness in phase change solid imaging materials and carrier compositions used to make phase change ink jet inks.
本发明公开了一种控制相变材料配方粘度的成分,该成分是通过将选定的亲核物(包括脂肪酸/醇反应物)与异氰酸酯反应制成的。加入异氰酸酯和不同的亲核剂将产生一种低粘度的粘度调节成分,可与较高分子量的聚酰胺树脂配制,以提高相变固体成像材料和用于制造相变喷墨墨水的载体组合物的韧性。
