ABSTRACT:
A non-wicking polyurethane casting system has been developed which comprises the reaction product obtained by admixing a polyol containing N-N-N'-N'-tetrakis (2-hydroxypropyl) ethylene diamine, (hereafter referred to as QUADROL) with an isocyanate terminated polyurethane based prepolymer. This non-wicking casting system is useful as a potting compound in biomedical applications such as dialysis and hemoultrafiltration devices and the like.
