Abstract

METODO DE PREPARACION DE MASAS DE MOLDEO DE RESINAS DE AMINOPLASTO. CONSISTE EN DISOLVER UN MONOFENILGLICOL EN UNA DISOLUCION ACUOSA QUE CONTIENE FORMALDEHIDO Y UN COMPONENTE DE CONDENSACION QUE CONTIENE GRUPOS AMINO, TAL COMO UREA O MELAMINA; Y SOMETER A REACCION DE CONDENSACION DICHA MEZCLA, A UNA TEMPERATURA INFERIOR A LA DE EBULLICION DE LA MEZCLA DE REACCION. ESTAS MASAS DE MOLDEO TIENEN APLICACIONES PARA LA FABRICACION DE PIEZAS MOLDEADAS ELECTRONICAS.
