Abstract

SE DESCRIBE EL PROCESO DE PREPARACION DE UN SUBSTRATO RECUBIERTO QUE TIENE UNA MEJORADA RESISTENCIA AL AMARILLEAMIENTO CONSISTENTE EN RECUBRIR UN SUBSTRATO CON UNA COMPOSICION DE REVESTIMIENTO DE UN COMPONENTE QUE CONTIENE A) UN POLIISOCIANATO EN BLOQUE RESULTADO DE LA REACCION DE UN POLIISOCIANATO CON UN AGENTE BLOQUEADOR DE OXIMA O LACTAMA PARA GRUPOS DE ISOCIANATO Y B) UN COMPONENTE CONTENIENDO COMO MINIMO DOS GRUPOS REACTIVOS AL ISOCIANATO, TENIENDO EN CUENTA QUE EL COMPONENTE A) Y/O EL COMPONENTE B) CONTIENE EL GRUPO -CO-(R)NN(R)-CO-, DONDE R REPRESENTA AL HIDROGENO O A UN RADICAL DE HIDROCARBONO OPCIONALMENTE SUSTITUIDO, EN CUANTIA DEL 0.01 AL 5% DEL PESO, BASADO EN EL CONTENIDO DE SOLIDOS DE LOS COMPONENTES A) Y B). LA COMPOSICION PARA REVESTIMIENTO DE UN COMPONENTE SE APLICA ANTES DE QUE ESTE SECA A UNA COMPOSICION DE REVESTIMIENTO QUE CONTIENE GRUPOS DE ACIDOS Y/O RESINAS DE MELAMINA QUE PREVIAMENTE SE HAN APLICADO AL SUBSTRATO O SE AÑADE UNA RESINA DE MELAMINA A LA COMPOSICION DEREVESTIMIENTO DE UN SOLO COMPONENTE ANTES DE APLICARLA AL SUBSTRATO, QUE DE MANERA OPCIONAL PUEDE HABERSE PREVIAMENTE RECUBIERTO. LA PRESENTE INVENCION TAMBIEN HACE REFERENCIA AL SUBSTRATO RECUBIERTO QUE TIENE RESISTENCIA MEJORADA AL AMARILLEAMIENTO PREPARADO MEDIANTE ESTE PROCESO.
