Abstract : The development of an aqueous polymer to function as the pigment binding vehicle for aircraft coatings was conducted. The third and final phase of effort was dedicated to synthesis and formulation of novel polymers to demonstrate the use of the solubility parameter design concept. The preferred system was identified as cationic polyurethane dispersions blended with epoxy resin crosslinking agents. Previous studies have identified a polyurethane of toluene diisocynate and a hydantoin diol as displaying excellent fluid resistance but poor flexibility. Evaluation of several hydroxy-terminated prepolymers for introduction of flexibility into this fluid resistance urethane provided a caprolactone polyester as the prepolymer of choice.
