USE OF TIMBER MATERIALS COMPRISING POLYAMINE FOR LOWERING FORMALDEHYDE CONTENT IN AMBIENT AIR

摘要

The present invention relates to the use of timber materials for the prod uction of furniture parts, wall coverings, insulation materials and the like , for lowering formaldehyde content in ambient air, where the timber materia ls (i) comprise polyamine as binder or (ii) comprise a binder other than pol yamine 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 polyamin e has at least 6 primary or secondary amino groups.
