Abstract (en)
[origin: WO2006117160A1] The invention relates to a method for waterproofing lignocellulosic materials by impregnating the lignocellulosic material with a waterproofing agent, whereby the lignocellulosic material is impregnated with a hardenable aqueous composition before or during waterproofing, said composition containing at least one cross-linkable compound, selected from a) low-molecular weight compounds V, having at least two N-bonded groups of formula CH<SUB>2</SUB>OH, wherein R = hydrogen or C<SUB>1</SUB>-C<SUB>4</SUB> alkyl, and/or one 1,2-bishydroxyethan-1,2-diyl group, bridging two nitrogen atoms, ß) precondensates of the compound V and ?) reaction products or mixtures of the compound V with at least one alcohol, selected from C<SUB>1</SUB>-C<SUB>6</SUB> alkanols, C<SUB>2</SUB>-C<SUB>6</SUB> polyols and oligo-C<SUB>2</SUB>-C<SUB>4</SUB>-alkylene glycols.
