Abstract

Procedimiento de preparación de una cola urea/formaldehído, caracterizado porque se mezcla una sal inorgánica a una fuente de formaldehído, porque se calienta y se hace reaccionar con urea para provocar un principio de polimerización en medio ácido, porque se para la reacción de polimerización cuando la mezcla ha alcanzado la viscosidad deseada, porque se adiciona urea a la mezcla en el curso de enfriamiento y porque se obtiene la cola después de enfriamiento.
