Abstract: An aqueous solution of a resin glue comprising formaldehyde, urea, melamine and phenol is obtained when phenol, formaldehyde and not more than 0.35 mole of an alkali metal bisulfite per mole of phenol are reacted to give a phenol-formaldehyde condensate, formaldehyde and urea in a molar ratio of not more than 2.5 are reacted to give a urea-formaldehyde condensate, and the reaction products are in turn reacted with melamine and formaldehyde.

Abstract: 1. A process for gluing solid wood with an adhesive based on a condensate of phenol, formaldehyde and resorcinol, or on a condensate of melamine, urea, phenol and formaldehyd, and co-used with a polysaccharide, wherein the adhesive and/or hardener mixture contains from 0.01 to 2.0% by weight of a D-galacto-D-mannan or a xanthane.

Abstract: A further embodiment of the process for the preparation of aqueous solutions of products of the condensation of formaldehyde and at least urea, melamine and phenol, in which the molar proportion of phenol, based on the sum of melamine and urea, is from 0.05 to 0.25, and the molar ratio between urea and melamine is from 0.2:1 to 1:0.2, at a total molar ratio between formaldehyde and the sum of melamine, urea and phenol of from about 1.1 to 2, the condensation products being usable as adhesive resins, in which, in each case in a manner known per se, phenol, formaldehyde and up to 0.35 mol of an alkali metal bisulphite per mol of phenol are reacted to form a phenol-formaldehyde condensate, and formaldehyde and urea are reacted in a molar ratio of 2.5 or less to form a urea-formaldehyde condensate, and the reaction products are themselves reacted with melamine and formaldehyde in such a ratio that the molar ratios between melamine, urea, phenol and formaldehyde mentioned at the outset are either produced directly or after a further reaction with up to 75% of the total intended amount of urea, in accordance with Patent Application P 3125874.3, characterised in that an effective amount of phenol of less than 0.05, based on the sum of melamine and urea, is proposed.
