Abstract: The invention relates to process of manufacture of wood products such as plywood and form pressed panels with improved production efficiency where an adhesive system (adhesive and hardener) is used together with a separate application hardener to facilitate the high production efficiency or production at reduced temperature or the combination of both. The process has at least 3 and preferably less than 50 alternating veneer layers A and B and comprises the steps of; - providing a glue mixture of adhesive I and hardener II on both sides of veneer layer(s) A; - providing a water based hardener III on both sides of veneer layers B; - laying-up in a stack at least one of said veneer layers A alternating with at least two veneer layers B - pressing the stack at elevated temperature and pressure to form the form-pressed product; and wherein said veneer layers A and B are stacked such, that the hardener III on veneer layers B get in contact with the glue mixture on veneer layer(s) A during pressing; and wherein the first and the last veneer in the stack should only have glue mixture or hardener solution on the inner side of the veneers, to avoid sticking in the press.

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 comprisinga 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 scavengerand 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/NH 2 ) between 0.2 and 0.7.

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.
