Abstract:
The present invention relates to a method of joining surfaces, comprising in the following order: applying an adhesive composition (A), comprising a solvent, onto a first surface, drying off the solvent, partially or completely, by forced drying, to give the adhesive composition (A) a solids content of X weight %, directly after the drying step, applying a component (C), comprising a solvent, having a solids content of Z weight %, onto a second surface, wherein Z
Abstract:
The invention relates to a method for gluing wood parts/components (10) by means of thermoplastic or duroplastic glue resins or glue resin systems. Before the wood parts/components (10) are glued, the entire cross-section (8) of the wood parts/components (10) is heated through evenly in an electromagnetic radiation field (9). The heated wood parts or wood components (10) are glued by the separate application of glue resin and hardener (binder) or of a mixed glue system consisting of glue resin and hardener.
Abstract:
A method of joining at least two objects (2, 4) by gluing with a two-component adhesive system to form a composite structure is disclosed. It comprises providing a first adhesive component including liquid urea-formaldehyde in combination with a powdery urea, so as to render the first component sufficiently viscous. Furthermore, a second adhesive component including a hardener is provided. At least one of the objects (4) is preheated prior to joining said objects. The first and second adhesive components are then applied separately to said objects. Finally, heat and pressure (14) is applied for a time sufficient to cause said adhesive to cure.
Abstract:
The invention is directed to assembly of a plurality of joined panel parts. Some of the individual parts contain a pre-applied curable adhesive to one or more sides or edges. An initiating metal activator is applied to complementing edges and cure is activated when the parts are assembled. The pre-applied adhesive system contains monomer(s), initiators, oligomers, an acid, and a sulfonyl compound. An activating or initiating metal foil, dispersion or coating is applied to the complementary surface. The bonding is effected when the adhesive system is activated by mating the edges. The activating metal is a reducible elemental transition metal. The metal is affixed to one surface which is brought into proximity with the curable adhesive compound dispensed onto the complementing part. The invention has usefulness in the joining of wood, wood products, composites of wood, thermoset polymer panels, non-initiating metal panels, and thermoplastic/wood composites, and the like to provide self-bonding assemblies having appearance surfaces, such as wall or floor coverings, especially assemblies that used joined board-like construction members.
Abstract:
A method of separate application of resin and hardener components of an amino resin gluing system onto a substrate, characterized in that the hardener comprises a volatile acid, and optionally a filler in an amount of less than 20 % by weight, wherein the components of the gluing system are applied in the form of strands or by means of spraying, or any combination thereof, in optional order of application. The invention also relates to a hardener composition for use in the method and to a device suitable for carrying out the method.
Abstract:
Adhesion of rubber to a variety of metals (aluminum, stainless steel, mild steel and brass) is effectively achieved by the application of an organofunctional silane (I) and a non-organofunctional silane (II) to the requisite surface. Preferably, the organofunctional silane (I) is a vinyltrialkoxysilane with the non-organofunctional silane (II) preferably comprising an alkoxylated substituted alkyl silane. The silanes (I) and (II) are at least partially hydrolyzed and are normally provided in the form of a EtOH/H2O solution. Bonded joints formed by these adhesive treatments can withstand fuel degradation tests indicating that the treatments can be used, for example, to bond metal and rubber surfaces in automotive and other environments in which the joined parts will be contacted by fuels, oil and/or organic solvents.

Abstract:
The present invention relates to a process for the production of wood products such as plywood and similar products. In the process a formaldehyde based curable adhesive is applied to a surface of a veneer layer and a separate hardener is applied to a surface of another veneer layer opposite to the one coated with adhesive. The separate hardener is applied in a zone along at least two edges of the surface which are opposite to each other. A number of veneers are coated in this manner and the veneers are then assembled to a package which is cold pre-pressed. The package is then cured by pressure and heat.
