Abstract

SE DESCRIBEN FUNDENTES PARA SOLDAR NO LAVABLES Y METODOS DE UTILIZACION DE LOS MISMOS. LOS FUNDENTES CONTIENEN DESDE ALREDEDOR DEL 1 % A ALREDEDOR DEL 4 % DE PESO DE AGENTES FUNDENTES. ESTAN PRESENTES AL MENOS DOS AGENTES FUNDENTES SELECCIONADOS DE ACIDOS MONOCARBOXILICO, DICARBOXILICO Y/O HIDROXI. SE INCORPORA SURFACTANTE NO IONICO EN LOS FUNDENTES EN UNA CANTIDAD MENOR DE ALREDEDOR DEL 1 % DE PESO. EL SISTEMA DISOLVENTE PUEDE SER AGUA DESMINERALIZADA SIN OTROS CODISOLVENTES O UN SISTEMA CODISOLVENTE COMPRENDIDO POR (I) AL MENOS ALREDEDOR DEL 90 % DE PESO DE AGUA DESMINERALIZADA BASADA EN EL PESO TOTAL DE LA SOLUCION DEL FUNDENTE PARA SOLDAR Y (II) DESDE ALREDEDOR DEL 1 % DE PESO A ALREDEDOR DEL 5 % DE PESO BASADO EN EL PESO TOTAL DE LA SOLUCION DE FUNDENTE PARA SOLDAR DE UN DISOLVENTE ORGANICO NO VOLATIL QUE FORMA UN CODISOLVENTE CON DICHA AGUA DESMINERALIZADA, DICHO DISOLVENTE ORGANICO NO VOLATIL TENIENDO UN PUNTO DE EBULLICION POR ENCIMA DE ALREDEDOR DE LOS 190 (GRADOS) C Y UNA PRESIONDE VAPOR POR DEBAJO DE 0,1 MILIMETROS HG A 25 (GRADOS) C.
