Abstract

Procedure for obtaining wet-resistant adhesives, especially for gluing paper, cardboard and objects formed from them, based on a mixture of alkaline split starch, at least a reaction product of urea and formaldehyde, and water, having the parts aqueous mixtures a final pH value of >= 10.5, characterized in that one molar part of urea is reacted with 0.5 to 1.6 molar parts of formaldehyde and 1 to 20% by weight of this reaction product is contacted with 99 to 80% in weight, in each case referred to the solids, of a facula solution or suspension at temperatures between 20 and 100ºC and is adjusted to a pH of = 10.
