Abstract

LA PATENTE AFECTA A UNA EVOLUCION DE LOS COMPONENTES DE RETICULACION PARA AGLOMERANTES CATIONICOS DE PINTURAS DESCRITOS EN AT - PS 382 384. EN ESTE PROCESO, LAS UREAS SUSTITUIDAS, OBTENIDAS MEDIANTE LA REACCION DE BETA - HIDROXAMINAS CON COMPUESTOS DE ISOCIANATO, SE TRANSFORMAN MEDIANTE REACCIONES POSTERIORES CON ISOCIANATOS EN COMPUESTOS DE BIURET. LOS COMPONENTES DE RETICULACION OBTENIDOS DE ESTA FORMA PROPORCIONAN CON RESINAS BASICAS (CON GRUPOS HIDROXILO Y/O GRUPOS AMINO PRIMARIOS O SECUNDARIOS) UNAS MEJORES PROPIEDADES DE PELICULA DEBIDO A UNA CAPACIDAD DE ENDURECIMIENTO ELEVADA, ESPECIALMENTE UNA MAYOR RESISTENCIA A LOS GOLPES DE PIEDRAS.
