Abstract

A method of effecting the reaction between resin components, with the aid of an amine catalyst, in the production of a material for molds or for the manufacture of cores in cast iron, characterized in that the catalysis is carried out at a pressure lower than the vapor pressure of the catalyst throughout the reaction.
