SE REFIERE A UN GUANTE MEDICO LIBRE DE POLVO QUE TIENE UNA PRIMERA SUPERFICIE DE UN COAGULANTE LIBRE DE POLVO Y UNA SEGUNDA SUPERFICIE CON UN REVESTIMIENTO DE POLIMERO PARA FACILITAR LA COLOCACION. EL COAGULANTE LIBRE DE POLVO EN LA PRIMERA SUPERFICIE COMPRENDE: POLIETILENO DE ALTA DENSIDAD MICRONIZADO, UNA MICRO-EMULSION DE AMINO SILICONA, UNA EMULSION DE DIMETICONA, SALES DE CALCIO, UN SURFACTANTE DIOL ACETILENICO ETOXILADO Y UN ESPESANTE DE CELULOSA. DICHOS GUANTES MEDICOS SE FABRICAN EN UN PROCESO EN LINEA PARA FABRICAR ARTICULOS DE LATEX QUE IMPLICA SUMERGIR MOLDES EN FORMA DE MANO EN EL COAGULANTE ANTES DE SUMERGIRLOS EN EL LATEX. PARA DESPUES REVESTIR LOS GUANTES CON UN POLIMERO ANTES DE RETIRARLOS DE LOS MOLDES, PARA MEJORAR LA CAPACIDAD DEL USUARIO PARA COLOCARSE LOS GUANTES. LA FORMULACION DE COAGULANTE PERMITE EL FACIL RETIRO DE LOS ARTICULOS DE LOS MOLDES, FACILITA EL USO DE DOBLE GUANTE Y ELIMINA LA NECESIDAD DEL PROCESAMIENTO FUERA DE LINEA A powder-free medical glove having a first surface of a powder-free coagulant and a second surface with a polymer coating to ease donning. The powder-free coagulant on the first surface comprises micronized high-density polyethylene, a micro-emulsion of amino silicone, a dimethicone emulsion, calcium salts, an ethoxylated acetylenic diol surfactant and a cellulose thickener. The medical gloves are made in an on-line process of making latex articles that involves dipping hand-shaped formers into the coagulant before dipping them into the latex. The gloves are thereafter coated with a polymer to improve donnability before removal from the formers. The novel coagulant formulation permits easy removal of the articles from the formers, eases double-donning of gloves and eliminates the need for off-line processing.
