Managing coil winding epoxy vacuum impregnation systems at the task level for increased yield, lower cost and extended performance

Liquid epoxy resin impregnation systems remain a contemporary, state-of-the-art polymer material for vacuum and vacuum/pressure applications in the manufacture of both advanced and conventional coil winding configurations. Their inherent latitude in processing parameters, to impart optimum cured properties to a given coil winding configuration, accounts for both their continued popularity in engineering applications and for the tendency to overlook or misinterpret the requisite processing parameters at the task level which must be managed in order to achieve optimum cured properties. A closer look reveals how understanding compound chemistry enables task level management of material acceptance, handling and storage, impregnation processing and cure management to increase manufacturing yield, lower unit cost and ensure optimum life cycle performance.
