Abstract
LA PRESENTE INVENCION SE REFIERE A LACAS EN POLVO SOBRE LA BASE DE POLIESTER CONTENIENDO GRUPOS CARBOXILO Y MEDIOS DE RETICULACION APROPIADOS. COMO MATERIAL FORMADOR DE PELICULA LA LACA EN POLVO CONTIENE UNA MEZCLA A PARTIR DE A) 70 HASTA 86 % EN PESO DE UNA MEZCLA A BASE DE UN POLIESTER O DE MULTIPLES POLIESTERES (A1) CON UN INDICE DE ACIDEZ EN LA ZONA DESDE 10 HASTA 150 MG DE KOH/G, CON PREFERENCIA EN LA ZONA DESDE 30 HASTA 100 MG/KOH/G, Y DE UN COMPONENTE (A2) DE MEDIO DE RETICULACION, QUE SE COMPONE DE COMPUESTOS CON UNA MEDIA SUPERIOR (A1) DE UN GRUPO EPOXI POR MOLECULA Y/O A BASE DE {BE} - HIDROXIALQUILO AMIDAS, DONDE LA RELACION DE LOS GRUPOS ACIDOS DEL POLIESTER O DE LOS POLIESTERES CON RESPECTO A LOS GRUPOS EPOXI Y/O A LOS GRUPOS {BE} - HIDROXIALQUILO AMIDA DE LOS COMPONENTES DEL MEDIO DE RETICULACION ALCANZA DESDE 0,6:1 HASTA 1,6:1, CON PREFERENCIA 0,9:1 HASTA 1,1:1 Y B) 30 HASTA 4 % EN PESO DE UNA RESINA DE POLIURETANO ACILADA O MULTIPLES RESINAS DE POLIURETANO ACILADAS O MULTIPLES RESINAS DE POLIURETANO ACRILADAS CON UN CONTENIDO EN COMPUESTOS DOBLES NO SATURADOS ETILENICAMENTE (CALCULADO COMO C = C, PESO MOLECULAR = 24) DESDE 2 HASTA 10 % EN PESO, CON PREFERENCIA DESDE 4 HASTA 6 % EN PESO, DONDE LA SUMA DE LA PORCION EN PESO DE LOS COMPONENTES A) Y B) ALCANZA 100 % EN PESO. LA PRESENTE INVENCION SE REFIERE ADEMAS A UN PROCESO PARA LA ELABORACION DE CHAPAS METALICAS RECUBIERTAS, DONDE SE UTILIZA PARA EL RECUBRIMIENTO LA LACA EN POLVO DE ACUERDO CON LA INVENCION.
