Abstract: A urea-formaldehyde resin is formed by (a) reacting formaldehyde and urea of an initial molar ratio of >=3, in an aqs. soln., pH 3, until 1% of the urea has reacted to form urone gps., or by reacting as above during a time t = 10pH-2 (between 90-100 degrees C), (b) adding urea to the obtd. prod., at pH=3, such that the polar ratio HCHO:urea is 2-2.75 and condensing until the aqs. soln. of the condensate is no longer indefinitely dilutable in water at room temp., and (c) concentrating or evaporating the soln. formed to give a prod. contg. HCHO and urea in a molar ratio 1-2.75. The resin is used partic. in the mfr. of plywood and has a reduced tendency to evolve free HCHO.

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.
