A curable resin comprising a mixture of (a) a component consisting of at least one thermically curable compound containing at least one 1-oxa-3-aza tetraline group, and (b) a component consisting of at least one curable brominated epoxy resin.

Curable resins comprising halogenated epoxy resins and 1-oxa-3-aza

Difficultly inflammable polymeric resins are obtained by curing resin mixtures comprising

Fire retardant curable 1-oxa-3-aza tetraline (also termed

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.

Method of bonding polyimide films and printed circuit boards

A resin which may be cured to form a polymeric resin which is diffcultly inflammable and resistant to high temperatures, said resin being a mixture of

The present invention generally relates to the mounting of panes or windshields in a frame, particularly to the mounting of panes or windshields of a vehicle, e.g. an automobile, in the body frame work. The invention provides a pane or windshield ready to be mounted comprising, along its edges, a first profiled bead of adhesive material, already cured and being elastic but not plastically deformable. The first bead comprises an essentially closed hollow chamber and 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 without the need to remove a cover foil or a packing prior to mounting the window.

Prefabricated pane or windshield for a vehicle

A composition comprising a polymeric resin derived from (A) at least one compound containing an average of more than one 1-oxa-3-aza-tetraline group per molecule with (B) at least one cycloaliphatic epoxide containing at least two epoxide groups, at least one of said epoxide groups being part of said ring, the mole ratio of (B) to (A) being in the range of about 0.2 to about 2.
