Abstract

Procedimiento de preparación de un catalizar reactivo para la policondensación de resinas amínicas usadas para aglomerar partículas celulósicas penetrables por agua, aumentando dicho catalizador la velocidad de policondensación de la resina si se usa en combinación con un catalizador conocido, mientras que, al mismo tiempo, permite el uso de cantidades inferiores de sólidos de resina sin comunicar pérdida alguna a la intensidad de aglomeración, procedimiento que comprende mezclar los componentes orgánicos e inorgánicos de dicho catalizador, siendo los componentes orgánicos formaldehído y urea o un producto de condensación no resinoso de formaldehído y urea, y siendo el componente inorgánico un haluro de metal alcalino soluble en agua, y formar una solución acuosa concentrada de la mezcla resultante de dichos componentes orgánicos e inorgánicos.
