摘要:
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.

Die Erfindung betrifft eine Verbindung zwischen zwei Paneelen (2,4), wobei beide Paneele (2,4) zumindest abschnittsweise miteinander korrespondierende Fügeflächen (6,8) aufweisen, die im verbundenen Zustand zumindest abschnittsweise aneinander anliegen. Das technische Problem, einerseits auf die Vorteile einer Klebeverbindung im Vergleich zu mechanischen Fügesystemen nicht zu verzichten, gleichzeitig aber den bauseitigen Aufwand und den Aufwand der Handhabung der Paneelen nicht zu erhöhen, wird dadurch gelöst, dass eine Matrix (14,16) auf mindestens einer der Fügeflächen (6,8) zumindest abschnittsweise angeordnet ist, dass eine Vielzahl von Kapseln (18) in der Matrix (14) verteilt angeordnet ist, dass in den Kapseln (18) ein Stoff eines Reaktionsklebstoffsystems enthalten ist und dass zumindest ein Teil der Kapseln (18) den in ihnen enthaltenen Stoff unter äußerer Einwirkung zumindest teilweise freisetzen. Die Erfindung betrifft auch eine Paneele mit mindestens einer Fügefläche sowie ein Verfahren zum Herstellen einer Klebermatrix auf einer Fügefläche.
摘要:
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.

The invention concerns a method of joining rail vehicle components and subassemblies by adhesion. This method combines the application of an adhesive which imparts permanent strength but hardens over a relatively long period of time with the application of an adhesive which rapidly imparts handling strength, complicated configurations of the joins to be stuck and high expenditure on equipment having to be avoided, manufacturing tolerances having to be compensated and specific minimum adhered join thicknesses having to be observed. Furthermore, the wetting with adhesive on selected join faces is to be restricted, without having to remove and dispose of the marginal borders. This problem is solved in that a rapidly adhering and inherently dimensionally stable first adhesive layer (4) is applied to first join faces (2.1, 3.1), and a second adhesive (5) which takes longer to harden is applied to second join faces (2.2, 3.2). The components are joined before or after the second adhesive layer (5) is applied, the first adhesive layer (4) rapidly imparting handling strength and maintaining a predetermined join spacing, whilst the second adhesive layer (5) fills the set join spacing and, after hardening, imparts permanent strength. The adhesive used for the first adhesive layer (4) is also used as a residual marginal border.

摘要:
A two-part composition curable by contact of respective parts with one another, comprising: a first part comprising a cationically polymerizable material and a first latent curing component; and a second part comprising a cationically polymerizable material and a second latent curing component which is reactive with the first component to form cations which are curingly effective for the resin. A preferred class of cation species comprises carbenium ions derived from reaction of organic halide compounds, as the first component, with silver salts of non-nucleophilic anions, e.g., SbCl₆⁻, SbCl₃⁻, SbF₆⁻, AsF₆⁻, SnCl₅⁻, PF₆⁻, BF₄⁻, CF₃SO₃⁻ and ClO₄⁻, as the second component. The respective parts of the two-part composition may be applied to matable surfaces which then are contacted to effect rapid bonding cure of the composition.

The invention relates to a reactive adhesive film system comprising a first reactive adhesive film (A) and a second reactive adhesive film (B); the use of the reactive adhesive film system described herein to glue together materials having non-polar surfaces; composite articles comprising the reactive adhesive film system; and methods for producing the reactive adhesive film system. Also described is a method for enhancing the adhesive properties of the reactive adhesive film system on non-polar substrates.
摘要:
Layers of an item may be temporarily assembled using a tacky surface on an adhesive layer. The adhesive layer may be activated by the application of energy to cause it to partially or entirely melt to bond layers together. The tacky layer may permit layers to be moved after initial positioning if the positioning is not acceptable. A tacky layer may cover all or part of the surface of an adhesive layer to permit the adhesive to flow without hindrance when activated.
