Abstract

Un adhesivo mejorado para hacer substratos adheridos que contiene: (a) por lo menos una resina epoxica, y (b) por lo menos un agente de curacion para la resina epoxica, pero (c) ninguna cantidad catalítica de catalizador para la reaccion entre la resina epoxica y el agente de curacion. Los substratos adheridos se usan para hacer compuestos al: (1) colocar uno o más de los subtratos adheridos en un molde; (2) inyectar en el molde una formulacion de resina madre que es químicamente similar al adhesivo, excepto que contiene una cantidad catalítica de catalizador para la reaccion entre la resina epoxica y el agente de curacion; y (3) cuara la formulacion de resina madre. Los adhesivos son más estables en el almacenamiento que adhesivos similares que contienen catalizador, y los compuestos resultantes tienen y/o retienen mejores propiedades físicas que los compuestos hechos usando adhesivos sin agente de curacion.
