A process by which aqueous, stable solutions of intermediate urea-formate condensates are prepared, which are obtained by reacting the urea and a formaldehyde solution under a neutral pH in the presence of an amount of alkaline earth chloride equivalent of 3 to 25% on the weight of the urea, or zinc chloride between 2 and 50% calculated on 100 parts of urea by weight, until reaching a viscosity of 0.08 to 0.21 poises. The product thus condensed is then neutralized and cooled, stopping the reaction. (Machine-translation by Google Translate, not legally binding)
