Abstract

OBJETO DEL INVENTO ES UN PROCEDIMIENTO PARA LA PRODUCCION DE UN ENVOLTORIO PERMEABLE SOBRE MATERIALES GRANULADOS SOLUBLES EN AGUA MEDIANTE EL RECUBRIMIENTO CON UNA RESINA SINTETICA. EN EL PROCEDIMIENTO DEL INVENTO SE USA UNA MASA DE REVESTIMIENTO QUE ABARCA UN POLIISOCIANATO Y UNA COMPONENTE DE POLIOLO DE UN PRODUCTO DE CONDENSACION FENOLEOS Y ALDEIDOS, UN PLASTIFICANTE QUE CONTIENE GRUPOS DE HIDROXILO Y EVENTUALMENTE UN DISOLVENTE QUE CONTIENE GRUPOS DE HIDROXILO. LA MASA DEL REVESTIMIENTO ENDURECE CON UNA AMINA COMO CATALIZADOR A TEMPERATURA AMBIENTE.
