Abstract

L'invention concerne des compositions de coulée de polyuréthane ne formant pas de mèches. Ces compositions comprennent le produit de réaction obtenu en mélangeant un polyol contenant de la N,N,N',N'-tétrakis (2-hydroxypropyl)éthylène diamine (<< Quadrol >>) avec un prépolymère à base d'urethane à terminaison isocyanate. Application : Ce système de coulée ne formant pas de mèches convient à titre d'agent d'enrobage pour des dispositifs biomédicaux, tels que des dispositifs de dialyse et d'hémoultrafiltration et similaires.
