摘要:
Radiation curable adhesives compositions and label assemblies are described which can be used in various labeling systems and methods. The adhesive compositions may be curable by exposure to UV radiation and are incorporated in the label assemblies. In certain versions, the label assemblies are free of liners otherwise covering the adhesive.

Die Erfindung betrifft eine Nutverschlussvorrichtung (7) zum Verschließen einer Nut (2) eines Stators (S) oder eines Läufers (R) einer elektrischen Maschine (E), mit einem Verschlusselement (4), das ein ferromagnetisches Material aufweist. Die Nut (2) soll mit wenigen Arbeitsschritten verschlossen werden können. An dem Verschlusselement (4) ist hierzu ein Klebeschicht (5) angeordnet, die ein thermisch aktivierbar ausgestaltetes Treibmittel (9) aufweist und die dazu ausgelegt ist, durch Erhitzen (H) aufzuquellen und auszuhärten, wodurch sie auch nach anschließendem Abkühlen der Kleber sein vergrößertes Volumen beibehält.
摘要:
The invention relates to a slot-closing device (7) for closing a slot (2) in a stator (S) or rotor (R) of an electric machine (E), said device (7) comprising a closure element (4) that contains a ferromagnetic material. The aim of the invention is to be able to close the slot (2) in a low number of steps. For this purpose, an adhesive layer (5) disposed on the closure element (4) contains a thermally activatable blowing agent (9) and is designed to swell and harden under the effect of heat (H) such that the adhesive maintains its expanded volume even upon cooling down.
摘要:
A thin, cured gel gasket is disclosed, including methods of making the thin gel gasket and the use of the thin gel gasket in an aircraft joint. In one embodiment, the thin gel gasket has no skeleton or other structure and is comprised of only a cured polyurethane gel and has a thickness of less than about 12 mill. It is manufactured using a release film that is adapted in a number of ways to make release from the gel prior to use easier. In one method of making and using the thin gel gasket. it is applied to a joint which is subject to compression, in one embodiment, a lap joint of an aircraft fuselage.

摘要:
The present invention relates to an adhesive system, comprising an adhesion promoter composition, containing at least one mercaptosilane, at least one polysilane, at least one transition metal complex comprising substantially only monodentate ligands, and at least one non-alcoholic solvent, and an adhesive, wherein the adhesive, within an hour after application and storage at 23°C and 50% relative air humidity, has a tensile shear strength of at least 3 MPa, as measured according to ISO 4587, and/or, within an hour after application and storage at 23°C and 50% relative air humidity, has at least 50%, preferably at least 60%, of the tensile shear strength achievable after application and storage for 7 days at 23 °C and 50% relative air humidity, as measured according to ISO 4587. The adhesive system according to the invention is suited, for example, for bonding glass panes in transport means and also builds up strength very quickly at low temperatures. The present invention further relates to an adhesion promoter system having a liquid container comprising a manually actuable output apparatus, and an adhesion promoter composition, as disclosed above.
