PURPOSE: To reduce a production time and cost and to obtain a solid amino resin of a low water content, by heating and reacting solid materials, and thereby making it possible to obtain a solid amino resin as a final reaction roduct, and to eliminate a formed dewatering step.
CONSTITUTION: Use is made of a solid amino compound, such as urea, melamine, or guanamine, alone, its mixture or modified product, or the like; a solid formaldehyde such as paraformaldehyde; and a solid catalyst such as hexamethylenetetramine, sodium hydroxide, or sodium chloride. If necessary, solid additives such as surfactants and lubricants are used. It is thus possible to obtain an amino resin as final product in the form of solid by heating and reacting these solid materials only.
