Abstract

Un procédé permettant de réduire les émissions de formaldéhyde issues de produits dotés d'une couche chargée de formaldéhyde. Ces produits comprennent au moins deux couches, une au moins étant constituée d'un panneau ou d'un placage, sachant qu'avant la liaison des différentes couches, au moins une surface latérale de ce panneau ou placage est traitée avec une solution contenant un sel renfermant du soufre anorganique. L'invention concerne également un panneau, un placage et un matériau de revêtement de sol obtenus par ce procédé ; une solution aqueuse contenant du sulfite d'ammonium ou du bisulphite et de l'urée et destinée à être utilisée dans ce procédé, et enfin un procédé de préparation de la solution aqueuse.
