The teachings herein are directed at solid polymeric adhesive compositions for adhering metal components, methods for compounding the polymeric adhesive compositions, articles including a component having the polymeric adhesive composition, methods for producing articles including curing a solid adhesive, and articles including the cured adhesive. Preferred solid polymeric adhesive compositions include a plurality of one or more epoxy resins and one or more polysulfones. In one preferred aspect, the teachings are directed at a stator ring (e.g., for a hybrid motor) including the polymeric adhesive composition for adhering components to a ring.

Solid polymeric adhesive compositions having high use temperature, and articles and methods thereof

Flexible films of thermosetting adhesive materials which are non-tacky to the touch are storage stable at room temperature and can be cured at elevated temperature with a short cure time and can be cured to produce a tough flexible adhesive layer including bonding to oily surfaces, the materials are particularly useful in bonding together dissimilar substrates.

Thermosetting adhesive films

The invention relates to structural adhesives and in particular to structural adhesives which are heat activated and which can be used for the bonding of components, particularly metal components, employed in the automotive industry.

Relating to structural adhesives

Relating to thermosetting adhesive films

Surfacesare bonded together by a heat activated adhesivethat is applied to a surfaceto cover an area greater than the area that is to form the bond, the two surfacesare brought together and the adhesiveactivated so that it creates the bond and also covers the exposed edges of the surfaces to provide an aesthetically pleasing and coatable corrosion and rust protective layer.

Production of joints

Means for joining two surfaces comprise providing a heat activated sealant () at the end of one of the surfaces and inserting the end into a C or U shaped cup in the end of the other surface and heating to cause the sealant () to flow and join the surfaces. Preferably the sealant () is foamable, the invention is particularly useful in the production of automobile hem flanges.

Method for producing a joint

A thermohardenable structural adhesive material that upon curing has an elongation at break of at least 10% and has a glass transition temperature (Tg) of 80&#xb0; C. or higher and is useful as a structural adhesive in automobiles to reduce the deformation of bonds particularly during accidents, the adhesive is dry to the touch at ambient temperature and can be melt processed at temperature below that at which thermohardening occurs. The adhesives are useful in applications requiring a combination of high strain to failure, glass transition temperature more than 80&#xb0; C., high stiffness and high strength. This combination is of particular interest in the aerospace and automotive industries.
