Abstract
The invention relates to a process for forming a wood-base product comprising the steps of a) providing particles of wood, b) resinating the particles of wood with a binder, c) compressing the resinated particles of wood to form a wood-base product, wherein before, during or after step b) the particles of wood and/or the binder are brought into contact with a broken dispersion. The invention also relates to the use of a polyfunctional compound as demulsifier for breaking a wax-containing dispersion. The invention further relates to a broken dispersion for hydrophobicizing lignocellulose-containing material. The invention additionally relates to a two-component system containing at least two components A and B: a wax-containing dispersion A) and a demulsifier B) having at least one functional group for breaking the wax-containing dispersion.
