Abstract
La presente invención se refiere a un método para curar una composición de orgasiloxano, este método caracterizado porque consiste esencialmente de: (1) calentar dicha composición a una temperatura de al menos 150 grados C, bajo una presión de al menos 9.8 kilopascales, por un período de tiempo suficiente para curar dicha composición, en que la composición comprende: (A) 100 parters en peso de un organopolisiloxano, con una fórmula unitaria promedio de RaSio(4-a)/2 donde R representa un radical de hidrocarburo monovalente, insubstituido o substituido, en que el substituyente es cuando menos un miembro seleccionado del grupo que consta de átomos de halógeno y grupos ciano, el valor promedio de a es de 0.8 a 2.2, y dicho organopolisiloxano contienen cuando menos 2 radicales de alquenilo en cada molácula; (B) un organohidrogenpolisiloxano, que tiene cuando menos 2 átomos de hidrógeno unidos al silicio en cada molécula, en una cantidad suficiente para proporcionar al menos 1 mol de átomos de hidrógeno unidos al silicio por mol de los radicales de alquenilo en el ingrediente (A); y (C) 5 a 200 partes en peso de sílice finamente dividido; y en donde la composición no contiene un catalizador de hidrosilación.
