An adhesive having a content of a thermically curable oxazene resin which contains at least one 1-oxa-3-aza tetraline group in the molecule, optionally in combination with at least one curable epoxy compound, is used for bonding polyimide films to films of the same kind or to other substrates, particularly metal foils. Such bondings are highly heat-resistant and have an excellent peeling resistance. Therefore, they are suitable for the manufacture of printed circuit boards having high thermal stability and peeling resistance.

The invention provides a method and an apparatus for discharging a substance contained in a cartridge or the like from the cartridge. The substance is prevented from flowing out by a sealing member provided at the outlet of the cartridge. To open the cartridge, a relative displacement between the cartridge and a coupling member mounted on the connection piece of the cartridge is effected to thereby open the sealing member by way of a cutting member provided in the coupling member. The sealing member is opened at least to such an extent that it releases the flow path of the substance contained in the cartridge fully or partially due to the pressure exerted on the sealing member by the substance contained in the cartridge during an initial phase of the discharge operation.

The present invention generally relates to the mounting of windows in a frame, particularly to the mounting of windows of a vehicle, e.g. an automobile, in the body frame work. The invention provides a method for manufacturing a window ready to be mounted comprising, along its edges, a first profiled bead of adhesive material, already cured and having the general cross section of a U-profile. This first bead is elastic but not plastically deformable. The first bead comprises in its interior a second bead of plastically deformable not yet cured adhesive material consisting of a substance chemically compatible to the material of the first bead. The second bead, serving as the real adhesive material, is protected from environmental influences e.g. by covering it by a protection foil which is removed just prior to mounting the window.

Method and apparatus for applying a curable material having variable curing characteristics to a surface in a defined application cycle which includes the steps of applying only a first slow curing component to the surface of an article at least at the beginning or at the end of an application cycle and applying during the remaining part of the application cycle a mixture of the slow curing component and a curing agent which accelerates the curing of the first component.

Process for application of a curable material to an article

A chemically-hardening two-component material based on polyurethane is provided, having a first component being a prepolymer with isocyanate end groups and a second component being a product which has been obtained from that prepolymer with isocyanate end groups by reacting it with a reactive compound which has at least two active groups, containing active hydrogen and which do not react identically with isocyanate. The prepolymer is a reaction product of an aliphatic or aromatic di-isocyanate with a polyol. Such a material can be produced by reacting a prepolymer which contains isocyanate end groups, with a second component, which, in turn, has resulted from a prepolymer with isocyanate end groups by reacting with a reactive compound which has at least two molecule groups, containing hydrogen and reacting differently with isocyanate. The material is especially suitable as a self-hardening gluing, coating, sealing and molding material.
