Abstract

A method for reducing the emission of formaldehyde from a foam material based on phenol-formaldehyde resin, in which process the foam material is treated with a solution of urea and thermally decomposable ammonium salt which ammonium salt gives off ammonia in substantial amounts in a temperature range of 15-90 DEG C. The solution contains 0.1-30 % by weight of urea and 0.1-25 % by weight of ammonium salt, the balance being water. The ammonium salt consists of ammonium carbonate or ammonium hydrogen carbonate or mixtures thereof.
