Abstract

Improvements introduced in the object of the main patent no. 401.248 on procedure to harden epoxy resins, by reaction of epoxy resins with anhydrous monomeric cyanamide in amounts of 0.3 to 0.6 moles per equivalent of epoxide, and accelerating agents, especially amines tertiary materials, and optionally fillers and/or reinforcing agents, especially fibers or fabrics optionally with pigments and auxiliary substances, and by transformation to the b-state in the temperature range from about 20 to 160ºC with subsequent cooling, characterized in that as a epoxy resins are used solid epoxy resins, prepared from bisphenols and epichlorohydrin, with equivalent epoxide weights of about 400 to about 1,200.
