Abstract

LA INVENCION SE REFIERE A UNA LACA DE ELECTROINMERSION ACUOSA CONTENIENDO UNA RESINA SINTETICA SEPARABLE CATODICAMENTE, CARACTERIZANDOSE PORQUE CONTIENE UN PRODUCTO (A) DE REACCION Y UN INICIADOR (B) DE POLIMERIZACION CON FORMACION DE RADICAL LIBRE. EL PRODUCTO (A) DE REACCION SE PREPARA MEDIANTE REACCION (A) DE UN POLIISOCIANATO O UNA MEZCLA DE POLIISOCIANATOS CON (B) UN COMPUESTO ORGANICO QUE CONTIENEN POR MOLECULA AL MENOS UN ENLACE DOBLE NO SATURADO ETILENICAMENTE, AL MENOS UN ATOMO DE HIDROGENO ACTIVO Y AL MENOS UN GRUPO AMINO TERCIARIO Y/O AL MENOS UN GRUPO CETIMINA Y/O ALDIMINA O UNA MEZCLA DE TALES ORGANICOS Y SE REQUIERE (D) UN COMPUESTO ORGANICO DIFERENTE DE (B) Y (C) QUE CONTIENE POR MOLECULA AL MENOS UN ATOMO DE HIDROGENO ACTIVO O UNA MEZCLA DE TALES COMPUESTOS ORGANICOS. LA REACCION EN VOLUMEN ENTRE LOS ACOMPAÑANTES DE REACCION ES TAL QUE 3 HASTA 80% DE GRUPOS NCO DEL COMPONENTE (A) REACCIONA CON EL COMPONENTE (B), 3 HASTA 80 % DE GRUPOS NCO DEL COMPONENTE (A) REACCIONA CON ELCOMPONENTE (C) Y 0 HASTA 94 % DE GRUPOS NCO DEL COMPONENTE (A) REACCIONA CON EL COMPONENTE (D). EL PRODUCTO DE REACCION ASI OBTENIDO SE DISPERSA EN AGUA. ANTES, DURANTE Y DESPUES DE LA DISPERSION, AL MENOS EL 5 % DE LOS GRUPOS AMINO TERCIARIOS Y/O PRIMARIOS CONTENIDOS EN EL PRODUCTO DE REACCION SON NEUTRALIZADOS CON ACIDO BRONSTED.
