Abstract: Wood materials with reduced subsequent release of formaldehyde can advantageously be produced by mixing lignocellulose-containing particles, for example wood chippings, with a curable binder based on curable aminoplastic condensates and subsequently pressing the mixture with heating, a mixture A containing a water-compatible agent for binding formaldehyde to the particles being applied or mixed with the particles before the particles are mixed with the curable binder, to give good resin reactivity, high strength and good swelling values if the mixture A is an aqueous solution having a pH of from 3.0 to 6.5 which contains a) organic acids which do not attack wood, or only do so to an insignificant extent, in an amount of greater than 15 % by weight, based on the solids content of the solution, preferably mixtures of aliphatic carboxylic acids having 4 to 10 carbon atoms, and b) a formaldehyde-binding, nitrogen-containing compound, in particular urea.

Abstract: Condensates containing urea and formaldehyde in a molar ratio of from 1:2.5 to 1:4.5 are converted into wood glue by allowing the viscosity to increase at a pH of from 1 to 3 and at only slightly elevated temperature and then adding urea at a pH of 7 to 9.
