Abstract:
The present invention relates to a method for spraying particulate solids onto a substrate, comprising the steps of: coating the substrate with a wet and/or adhesive synthetic resin layer, building up a gas pressure in a line, generating a pressure differential in the line, swirling and carrying along particulate solids in the line, ejecting swirled, particulate solids from the line onto the surface of the wet and/or adhesive synthetic resin layer of the substrate. The invention also relates to a substrate, in particular a wood-based panel or decorative paper, at least partially coated with a particulate solid, characterized in that the particulate solid is applied to the substrate with an accuracy of up to ±0.8 g/m2, preferably of up to ±0.5 g/m2, particularly preferably of up to ±0.3 g/m2, preferably of up to 0.1 g/m2.

Abstract:
The present invention relates to new formulations for adhesive compositions and also to adhesive compositions particularly for a hybrid adhesive comprising at least one mixture of an amino resin and at least one polyether, and the combination of this mixture with isocyanate, and also to the use of polyethers in adhesives based on amino resins. These adhesive compositions are especially suitable for use as adhesives for woodbase materials, more particularly OSB boards, fiberboards, or chipboards. In a further aspect the present invention relates to processes for producing such woodbase materials from lignocellulosic products of comminution, more particularly to processes for producing OSB boards, wood fiberboards, or chipboards, where the lignocellulosic products of comminution are contacted with the adhesive composition of the invention and subsequently the woodbase materials are obtained by pressing with heat treatment. Lastly, the present invention is directed to woodbase materials obtainable accordingly.
Abstract:
The invention relates to a method for producing a glue-coated element, to the glue-coated element, to an adhesive compound and to a method for producing glue-coated derived timber panels, as well as to panels produced according to the method. The method for producing a glue-coated element that can be glued with other similarly glue-coated elements, comprises the steps of applying a one-component adhesive to at least one surface section of the element and drying the applied one-component adhesive. According to a preferred embodiment of the invention, draw-out resistance elements are provided on the glue-covered element.
Abstract:
A process for production of wood-base materials from lignocellulosic comminution product is disclosed. The wood-base materials are treated with at least one additive in the course of their production to reduce or diminish the emission of volatile organic compounds (VOCs) and, optionally, very volatile organic compounds (VVOCs), in particular terpenes and acids. The treatment is effected with one additive, being a porous carbon, like activated carbon. In another aspect, the present application is directed to the use of porous carbon, in particular, activated carbon, to reduce or diminish the emission of VOC, and optionally, VVOC, to reduce or diminish the emission of terpene and acids and aldehydes. Also, wood-base materials which are obtainable with the process or wood-based materials produced by using the additives mentioned above and which have reduced emission of VOCs, in particular terpenes and acids but also aldehydes are disclosed.
Abstract:
The present invention relates to the use of modified nanoparticles in wood based panels, in particular OSB-panels for reduction of the emission of volatile organic compounds (VOCs). The invention further relates to a wood based panel containing the modified particles and to a method for producing such a wood based panel.

Abstract:
The invention relates to an adhesive bond between two elements each having a dried adhesive film (26, 34) of a one-component adhesive applied to it in the factory, wherein the adhesive films (26, 34) have merged into a single adhesive layer, and further including a mechanical draw-out resistance element extending from a first element of the two elements toward a second element of the two elements.
