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 containing an aqueous phase as continuous phase, a disperse phase containing wax and at least one emulsifier. The invention further relates to a broken dispersion for hydrophobicizing lignocellulose-containing material, wherein the broken dispersion is obtainable by mixing at least mixed a wax-containing dispersion A) containing the following components: i) at least one aqueous phase as continuous phase, ii) at least one disperse phase containing wax, and iii) at least one emulsifier, with a demulsifier B) having at least one functional group. The invention additionally relates to a two-component system (kit-of-parts) containing at least two components A and B: a wax-containing dispersion A) containing at least one aqueous phase as continuous phase, at least one disperse phase containing wax, and at least one emulsifier, and a demulsifier B) having at least one functional group for breaking the wax-containing dispersion. |
