Abstract: PROBLEM TO BE SOLVED: To provide a means to create a tougher phase change formulation with a component that control its viscosity by using an isocyanate-derived material to control the viscosity for a relatively low viscosity resins including nonpolymeric resins, and waxes, designed for phase change ink jet and other forms of phase change material printing and rapid prototyping applications, especially those requiring materials with increased toughness as new materials for novel and different application of the phase change materials. SOLUTION: This formulation for use in jetting from a print head comprised (a) a component to control the viscosity of the formulation, the component being linear alkyl urethane, (b) a component to promote adhesion to a substrate, (c) a component to impart toughness to the formulation, and (d) a component to control shrinkage of the jetted formulation.
