Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA LA OBTENCION DE COMPOSICIONES EN POLVO DE PINTURAS DISOLVIENDO UNA O VARIAS RESINAS BASICAS Y UNO O VARIOS ENDURECEDORES, QUE SE ENCUENTRAN EN FORMA SOLIDA, CON UN COMPUESTO DE BAJO PESO MOLECULAR, QUE SE ENCUENTRA POR ENCIMA DE SU PRESION Y TEMPERATURA CRITICAS, ESTE COMPUESTO ES INERTE CON RESPECTO A LAS RESINAS BASICAS Y ENDURECEDORES Y SE ENCUENTRA EN FORMA GASEOSA EN CONDICIONES NORMALES DE PRESION Y TEMPERATURA; A CONTINUACION SE REDUCE LA PRESION DE LA SOLUCION RESULTANTE. ESTO SE PUEDE REALIZAR POR EJEMPLO POR PULVERIZACION; LA COMPOSICION DE PINTURA EN POLVO RESULTANTE SE PUEDE PULVERIZAR DIRECTAMENTE SOBRE EL SUSTRATO QUE SE VA A RECUBRIR. LAS PINTURAS EN POLVO SE PUEDEN RECICLAR SEGUN EL PROCEDIMIENTO DE LA INVENCION.
