The present invention relates to the use of timber materials for the production of furniture parts, wall coverings, insulation materials and the like, for lowering formaldehyde content in ambient air, where the timber materials (i) comprise polyamine as binder or (ii) comprise a binder other than polyamine and also, in or on the outer layers of the timber material, polyamine, and the molar mass of the polyamine is at least 500 g/mol and the polyamine has at least 6 primary or secondary amino groups.
La présente invention concerne l'utilisation de matériaux dérivés de bois pour la fabrication d'éléments de meubles, de panneaux muraux, de matériaux d'isolation et analogues destinés à diminuer la teneur en formaldéhyde dans l'air ambiant. Selon l'invention, les matériaux dérivés de bois (i) contiennent une polyamine en tant que liant ou (ii) contiennent un liant autre que la polyamine et comportent aussi une polyamine dans ou sur les couches externes de matériau dérivé de bois. La polyamine présente un poids moléculaire supérieur ou égal à 500 g/mol et comporte au moins 6 groupements amino primaires ou secondaires.
