摘要： Expandable thermosettable compositions containing at least one epoxy resin, at least one finely divided thermoplastic polymer powder, at least one blowing agent, at least one curing agent, and at least one filler are suitable for the production of thermosetting laminated bodies with a tacky surface. These laminated bodies can be produced and handled in a simple manner and are suitable for stiffening and reinforcing flat structural components, in particular vehicle body structural components, such as vehicle body frames, doors, trunk lids, engine hoods and/or roof components in automobile construction. The expandable thermosettable compositions are also suitable for the production of thermosetting, thermally expandable shaped articles for reinforcing hollow structural members by the injection molding process. In preferred embodiments, the composition is injected onto a metallic or thermoplastic carrier. These thermally expandable shaped articles are especially useful in the production of automobiles and other vehicles to maintain or increase the strength of structural members such as rockers, pillars, radiator support beams, doors, reinforcing beams, and the like.

摘要： This invention relates to compositions useful as adhesives and more particularly to the preparation of heat-curable epoxy-based adhesive compositions that are resistant to being washed off substrate surfaces prior to being cured. The incorporation of a solid diene-based rubber, in particular an acrylonitrile-butadiene copolymer rubber having a relatively high Mooney viscosity, significantly enhances the wash-off resistance of the adhesive, while still allowing the adhesive to be readily dispensed by pumping under high shear conditions.

摘要： The present invention is directed to a high expansion two-component structural foam that expands to about twice its original volume while maintaining good cell structure. The foam of the present invention is based on epoxy resins. Each component of the foam system exhibits storage stability, e.g., no phase separation, yet reacts when combined to provide a cured material having exceptionally good compression strength and modulus. The blowing system used to prepare the foam produces a foam which is uniform in appearance and is essentially free of the large voids often found in conventional two-part thermosettable compositions, even when a relatively large mass is utilized.
