Abstract

SE DESCRIBE UN METODO PARA PREVENIR EL AMARILLEO DEL REVESTIMIENTO MAS EXTERIOR DE UN SISTEMA DE REVESTIMIENTO MULTICAPAS. EL METODO CONSISTE EN DEPOSITAR INICIALMENTE DENTRO DE UN SUBSTRATO CONDUCTOR, MEDIANTE ELECTRODEPOSICION CATODICA, UN PRIMER REVESTIMIENTO QUE COMPRENDE POR LO MENOS UNA CAPA DE UN ADUCTO DE RESINA DE AMINA-EPOXI Y UN AGENTE DE ENTRECRUZAMIENTO Y LUEGO CURAR A UNA PELICULA DURA, DURADERA. LUEGO, DEPOSITAR UN SEGUNDO REVESTIMIENTO SOBRE EL PRIMERO, QUE COMPRENDE POR LO MENOS UNA CAPA DE UN RECUBRIMIENTO BASE FORMADOR DE PELICULA PIGEMNTADO. LUEGO, DEPOSITAR UN TERCER RECUBRIMIENTO MAS EXTERIOR SOBRE EL SEGUNDO, QUE COMPRENDE POR LO MENOS UNA CAPA DE PROTECTOR, FORMADOR DE PELICULA, CLARO, Y LUEGO CURAR EL RECUBRIMIENTO BASE Y EL PROTECTOR. EL PRIMER RECUBRIMIENTO CONTIENE UN AGENTE DE ENTRECRUZAMIENTO ELEGIDO DEL GRUPO QUE CONSTA DE POLIISOCIANATOS ALIFATICOS, QUE CONTIENEN POR LO MENOS 6 ATOMOS DE CARBONO, CONTENIENDO LOS ISOCIANATOS DE LOS POLIISOCIANATOS ALIFATICOS POR LO MENOS 6 ATOMOS DE CARBONO, TENIENDO LOS POLIISOCIANATOS AROMATICOS Y LOS ISOCIANATOS DE DIISOCIANATOS AROMATICOS UN PESO MOLECULAR MAYOR QUE 177. LOS POLIISOCIANATOS E ISOCIANATOS SON BLOQUEADOS CON UN AGENTE DE BLOQUEO.
