Abstract

A method for reducing the emission of formaldehyde from particle board using carbamide resin as binder. After the pressing, the sheets are coated with a solution of a) urea and preferably ammonium carbonate and/or ammonium hydrogen carbonate and possibly c) ammonium acetate and are then cured.
