Abstract

Cette invention concerne un procédé pour le durcissement de résines époxydes avec du cyanamide. On répartit de façon homogène une solution aqueuse de cyanamide ou d'un mélange de cyanamide avec une quantité d'urée pouvant aller jusqu'à 75 % en poids dans la résine, et on durcit ce mélange homogène, le cas échéant en présence d'accélérateurs. Ce procédé permet d'obtenir notamment des stratifiés de bonne qualité à partir de solutions aqueuses de cyanamide ou de cyanamide et d'urée.
