The invention concerns an adhesive system comprising (a) a resin component comprising a urea based amino resin having an F/NHratio from 0.3 to 0.65; (b) a hardener component comprising at least one acid, acid generating salt or acidic salt; and, (c) an aqueous polymer dispersion; wherein the adhesive system comprises no or less than 0.9 wt % of urea, based on the weight of the entire adhesive system, in addition to any urea present in the urea based amino resin. The invention further concerns a method of producing a wood based product, wood based products obtainable thereby and use of the adhesive system.

Adhesive system

The present invention relates to a method of a method of producing a wood-based product, comprising, in the following order: applying an adhesive composition comprising a solvent, onto the first surface only, drying and heating the adhesive composition applied to the first surface, wherein the solvent is partially dried off, and bringing together the first surface with the second surface, and pressing the two surfaces against each other.

Method of joining surfaces

The present invention relates to a method of joining surfaces, comprising in the following order: applying an adhesive composition (A), comprising a solvent, onto a first surface, drying off the solvent, partially or completely, by forced drying, to give the adhesive composition (A) a solids content of X weight %, directly after the drying step, applying a component (C), comprising a solvent, having a solids content of Z weight %, onto a second surface, wherein Z&#x3c;X, bringing together the two surfaces so that the adhesive composition (A) is in contact with the component (C), and, pressing the two surfaces against each other. It also relates to a method of producing a wood based product.
