Flexible, sheet-like substrates having an abrasive surface, which are obtainable by applying an aqueous solution or dispersion of at least one precondensate of a heat-curable resin to the top and/or bottom of a flexible, sheet-like substrate in an amount of at least 5 to 90% by weight, based on the uncoated, dry substrate, crosslinking the precondensate and drying the treated substrate.

Flexible, flat substrates having an abrasive surface

A light wood-containing material having an average density in the range from 200 to 600 kg/m, comprising, based in each case on the wood-containing material:

Process for the preparation of etherified melamine/formaldehyde condensates, in which first a methylolation of melamine with a formaldehyde component in the molar ratio of from 1:6 to 1:15, preferably at a pH of &#x3e;7, is carried out. This is followed by an etherification of the resulting hydroxymethylation intermediate in the presence of a C-C-alkyl, preferably of a C-C-alcohol, particularly preferably of a C-C-alcohol, at a pH of &#x3c;4.5, and subsequently by at least one distillation step in order to remove in particular methanol from the system, the pH of &#x3e;9.5 being established before, during and/or after the distillation. According to the invention, a plurality of hydroxymethylation, etherification and distillation steps follow in order to achieve an etherified melamine/formaldehyde condensate which is distinguished by a high degree of hydroxymethylation, a high solids content and a low viscosity.

Etherified melamine/formaldehyde condensates having a high solid content and low viscosity
