  • Publication number: 20140014267
    Abstract: The invention relates to an improved two component adhesive system, a kit comprising said two adhesive components, its use and a method for production of interior wood products, in particular form-pressed products, parquet floor elements and solid wood panels with very low formaldehyde emission and to the interior wood products obtainable having improved properties. The two-component adhesive system comprises adhesive component I comprising a 50-70 wt % melamine-formaldehyde (MF) type resin in 25-40 wt % water and adhesive component II comprising 25-40 wt % of a water based dispersion adhesive, 15-40 wt % of a formaldehyde scavenger and an acidic compound in an amount such that the pH of adhesive component II is 1.5-6.5, wherein adhesive component I and II are to be applied in a weight ratio I:II of 1:0.5 to 1:1.5 and the adhesive system has a molar ratio of formaldehyde (F) to total amino group (F/NH2) between 0.2 and 0.7.

  • Publication number: 20040099373
    Abstract: A process for gluing laminated products with a curing amino adhesive, such as melamine urea formaldehyde (MUF) adhesive or urea formaldehyde (UF) adhesive, wherein a hardener comprising acid, acid salt and/or acid generating salt and a polymer dispersion or a mixture of different polymer dispersions and conventional additives, and the adhesive are applied separately at the parts to be glued, that the parts thereafter are joined and that the glue thereafter is cured under pressure, is described. Additionally, a use of a polymer dispersion or a mixture of different polymer dispersions in a hardener for use in a method for separate application of adhesive and hardener is disclosed.
