Abstract: A method for controlling the production of formaldehyde resin compositions in which formaldehyde takes part in a reaction with one or a combination of co resin forming material (of the type phenol, urea, melamine) the method includes monitoring at least one of the formation of the reaction mixture and the course of the reaction by near-infrared (NIR) spectroscopy and adjusting the course of the reaction (when necessary) in accordance with the results of the spectroscopy to obtain optimum conditions for the reaction.
