Abstract

EL INVENTO SE REFIERE A UN EXCIPIENTE DISPERSABLE EN AGUA PARA EL BARNIZADO ELECTROLITICO Y CATIONICO POR INMERSION, A UN PROCEDIMIENTO PARA LA PRODUCCION DEL EXCIPIENTE Y A UN METODO PARA EL RECUBRIMIENTO ELECTROFORETICO DE UN SUBSTRATO CONDUCTOR DE LA ELECTRICIDAD CONECTADO COMO CATODO EN UN BAÑO ACUOSO A BASE DEL EXCIPIENTE. EL EXCIPIENTE DISPERSABLE EN AGUA ES UN PRODUCTO DE REACCION DE (A) RESINAN EPOXIDICAS CON UN 10 A 6% EN PESO DE UNOS PREPOLIMEROS (B). EL PRODUCTO DE LA REACCION SE TRATA CON AMINAS (C) PRIMARIAS, SECUNDARIAS Y TERCIARIAS Y/O SUS SALES O UNA MEZCLA/ACIDO-SULDURO O UNA MEZCLA-ACIDO/FOSFINA PARA LOGRAR LA DISPERSABILIDA ACUOSA. LAS RESINAS EPOXIDICAS CONTIENEN GRUPOS AROMATICOS EN 10 A 45% EN PESO DEL TOTAL, TIENEN UN PESO MOLECULAR BAJO Y UN PESO EQUIVALENTE DE EPOXIDICO INFERIOR A 750. LOS PREPOLIMEROS TIENEN UN PESO MOLECULAR ENTRE 50 Y 5000 Y PRESENTAN ENTRE 0,1, A 1,9 GRUPOS HIDROXILICOS POR MOLECULAS Y ENTRE 0,1 A 1,0 GRUPOS CARBOXILICOS POR MOLECULA CON LA CONDICION QUE LA SUMA DE LOS GRUPOS HIDROXILICOS Y CARBOXILICOS ESTE COMPRENDIDA ENTRE 1 Y 2. ADEMAS LOS PREPOLIMEROS CONTIENE GRUPOS AROMATICOS (GRUPOS FENILENO) EN UN 10 A 45% EN PESO.
