Abstract

1. Use of a curing agent based on an ammonium salt of a strong acid and, if required, urea, which curing agent contains form 10 to 50% by weight of a sheet silicate, from 0.3 to 3% by weight of a starch powder or from 10 to 50% by weight of a dextrin and from 0.1 to 2% by weight of xanthan, the percentages being based on its dry components, for urea/formaldehyde or melamine/urea/formaldehyde resin glue liquors which are used for gluing the surfaces of woodworking materials.
