  • USE OF TIMBER MATERIALS COMPRISING POLYAMINE FOR LOWERING FORMALDEHYDE CONTENT IN AMBIENT AIR
    Publication number: 20100022679
    Abstract: The present invention relates to the use of wood-base materials for the production of furniture parts, wall claddings, insulation materials and the like for reducing the formaldehyde content in the ambient air, the wood-base materials (iii) comprising polyamine as a binder or (iv) comprising a binder differing from polyamine and additionally having polyamine in or on the outer layers of the wood-base material and the polyamine having a molecular weight of at least 500 g/mol and at least 6 primary or secondary amino groups.

  • Fiberplates made of polyamines or polyamine-containing aminoplast resins as binding agents
    Patent number: 6624284
    Abstract: A process for producing fiberboard panels includes I. gluing cellulosic fibers with an aqueous glue solution and adjusting the moisture content of the cellulosic fibers and/or the water content of the glue such that the moisture content of the glued cellulosic fibers is not more than 150%; and II. compressing the glued cellulosic fibers produced in step (I) at elevated temperature to fiberboard panels.
