When foamed and adhered to a metal substrate surface, such polyester-modified foamable compositions can exhibit improved adhesion to the substrate surface after exposure to a corrosive environment, as compared to compositions that do not contain polyester. Furthermore, these compositions can exhibit improved flow properties in the uncured state at temperatures between 50 and 100° C. They are granulatable, with the granules produced thereby having non-tacky surfaces at room temperature and being capable of being readily processed into molded objects by injection molding processes.Type: ApplicationFiled: December 8, 2008Publication date: July 9, 2009Applicant: HENKEL AG & CO.

Patent number: 7473717Abstract: 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.Type: GrantFiled: June 14, 2004Date of Patent: January 6, 2009Assignee: Henkel AG & Co.

Patent number: 7473715Abstract: The present invention relates to methods, materials, and products for forming a foamed product, comprising the steps of combining an epoxy-based component with an amine-based component. The epoxy component is cross-linked through a polymerization reaction catalyzed by the amine formulation. In this regard, an reactive mixture or exothermic reaction is created between the epoxy component and the amine component when combined. The heat generated by the exothermic reaction softens a thermoplastic shell of a blowing agent formulated within the epoxy component thereby enabling a solvent core within the thermoplastic shell of the blowing agent to expand from the heat generated by the exothermic or reactive mixture.Type: GrantFiled: November 10, 2004Date of Patent: January 6, 2009Assignee: Zephyros, Inc.Inventors: Michael J.

Patent number: 7119149Abstract: 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.Type: GrantFiled: January 3, 2003Date of Patent: October 10, 2006Assignee: Henkel Kommanditgesellschaft AUFInventors: Gregory A.

Patent number: 7114503Abstract: The invention relates to a foam for purifying and filtrating air, particularly filtrating toxic compounds, such as for instance tar and polycyclic aromatic hydrocarbons (PAHs) from tobacco smoke, and to a method to prepare this foam. The foam according to the invention is a foam comprising cavities and interstitial spaces situated outside of the cavities, the cavities being defined by walls, the walls of the cavities being composed of a crosslinked polymer and possible additives, the average largest dimension of the cavities being in the range of 30–350 ?m, a considerable part of the cavities comprising two or more perforations in their walls, the perforations having an average diameter in the range of 5–300 ?m, a considerable part of the perforations of adjacent cavities being positioned with respect to each other such that a continuous, non-linear path is formed, the foam having a porosity of at least 45 vol.Type: GrantFiled: May 12, 2003Date of Patent: October 3, 2006Assignee: B.V.
