POLYURETHANE FILMS PREPARED BY ELECTRODEPOSITION FROM POLYURETHANE DISPERSIONS

摘要

A process is described for preparing Polyurethane Films, which includes Electroplating Film on a substrate from a polyurethane dispersion,An advantage of the electrodeposition process of the present Invention is that an additional step is necessary to remove coagulants of filmsAs conventional coagulation processes. Another advantage is that use the electrodesposicion, the quantity of water that must be removed during a step of dehydration reduces alminimo.A Third advantage is that the resulting Film shows Greater uniformity in thickness as compared to films prepared through conventional coagulation techniques.The present Invention has applicability in, for example, Medical Applications.
