Abstract: A process for bonding lignocellulose raw materials using an isocyanate group-containing urethane-modified diphenylmethane diisocyanate mixture having a viscosity of 120 to 1000 mPas at 25 DEG C. and an isocyanate content of 15 to 33.6 percent by weight which is obtained by reacting a diphenylmethane diisocyanate mixture containing 10 to 75 percent by weight of 2,4'-diphenylmethane diisocyanate with 0.05 to 0.5 hydroxyl equivalents of a polyol per equivalent isocyanate group.

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.

Abstract: Chipwood working materials are produced by pressing the chips or other comminuted cellulose-contng. product obtained from plant raw materials, with sulphite washings as a binder. 10-30% amino-plastic condensate are added to the binder in accordance with DT1223534. The chips have an aqueous dispersion of phenoplastic condensate, and the quantity of these chips having amino-plastic condensate amount to 10-50% of the total quantity.
