    Abstract: Disclosed are aqueous binder mixtures suitable for producing derived timber products and containing (A) an aqueous aminoplast resin consisting of (a1) melamine, (a2) 0.8 to 6 mol urea per mol melamine, (a3) 2 to 20 mol formaldehyde per mol melamine and (a4) 0 to 1 mol of another compound that can react with formaldehyde in an addition reaction or condensation reaction and is different from phenol or a condensation-polymerizable phenol derivative, per mol melamine, and (B) 0.55 to 0.75 mol urea per mol of the total amount of urea used as components (a2) and (B), with the proviso that the molar ratio of the melamine (component (a1)) to the total amount of urea (components (a2) and (B)) is 1:3.5 to 1:13 and that the molar ratio of formaldehyde (component (a3)) to the -NH2 groups in components (a1), (a2) and (B) is 0.2:1 to 0.7:1.

    Abstract: The invention concerns binders containing: A) an aminotriazine derivative in which the triazine primary amino groups are methylolated on average with at least one mol of formaldehyde per mole of primary amino groups and these methylol groups are etherified on average with at least 0.5 mole primary alcohol per mole of methylol group, and the primary alcohols are a mixture containing: a) 0.5 to 99.5 mol % of a C1-C4 alkanol and b) 99.5 to 0.5 mol % of an alcohol of the formula (I) R -O-[R -O]n-R -OH, in which R stands for a C1-C24 alkyl group or a C6-C12 aryl group which may optionally be substituted by one to three C1-C8 alkyl groups, and R and R , independently of each other, stand for a C2-C8 alkylene group, and n means an integer from 1 to 100, or a mixture of higher-boiling alcohols having a boiling point of more than 120 DEG C at 1 bar, which contains at least 10 mol %, relative to the higher-boiling alcohols, of alcohols of formula I; and B) a radical polymer, which can be crosslinked with the aminotriazine derivative, a polycondensate or polymer additive.
