US Patent:

6348513, Feb 19, 2002

Filed:

May 4, 1999

Appl. No.:

09/305013

Inventors:

Bradley L. Hilborn - Ferndale MI
Bruce Lee Harrison - Sterling Heights MI

Assignee:

Henkel Corporation - Gulph Mills PA

International Classification:

C08J 906

US Classification:

521 95, 521 94, 521135, 521178, 523219

Abstract:

Foamable compositions which exhibit reduced surface tack and better handling characteristics are obtained through the use of specific combinations of epoxy resins. One or more solid epoxy resins are utilized together with liquid and/or semi-solid epoxy resins. The compositions, which preferably contain hollow glass microspheres, are capable of providing foams which are useful in the manufacture of reinforced structural members.

Appl. No.:

09/260421

Inventors:

Bruce Lee Harrison - Sterling Heights MI

Assignee:

Henkel Corporation - Gulph Mills PA

International Classification:

C08J 932

US Classification:

521 54, 521 95, 521135, 521178

Abstract:

Foamable compositions based on epoxy resins which exhibit good shelf life are obtained through the use of specific blowing agent and curing accelerator systems. The blowing agent system contains azodicarbonamide, while the curative system contains an amine-epoxy adduct such as an imidazole-epoxy adduct. The compositions are capable of providing structural foams which are useful in the manufacture of reinforced structural members and the like.

Appl. No.:

09/668671

Inventors:

Bruce L. Harrison - Sterling Heights MI

Assignee:

Henkel Corporation - Gulph Mills PA

International Classification:

B32B 2738

US Classification:

428418, 428413, 4283044, 4283133, 521 76, 521 82, 521 98, 521 99, 521128, 523400, 523465

Abstract:

Waxes, particularly paraffin and microcrystalline waxes, can act as corrosion inhibitors when added at low levels to compositions based on thermosettable resins such as epoxy resins. When such wax-modified thermosettable compositions are used to coat a metallic surface, enhanced protection of the metallic surface against corrosion due to environmental exposure such as salt spray is obtained. The thermosettable compositions are particularly useful in expandable or foamable form for imparting structural reinforcement to hollow metal parts such as automotive components.

Appl. No.:

09/437395

Inventors:

Bruce Lee Harrison - Sterling Heights MI
George F. Didlake - Troy MI

Assignee:

Henkel Corporation - Gulph Mills PA

International Classification:

B32B 2704

US Classification:

4282974, 4282997

Abstract:

A thermosettable adhesive is used to secure a laminate having a compliant layer (for example, a foamable composition containing a diene rubber), a layer comprised of a thermosettable resin capable of being cured to a rigid state, and an optional carrier layer (for example, a metal foil) to a substrate for the purpose of strengthening, stiffening, or otherwise reinforcing the substrate. The substrate may, for example, be a metal vehicle door. The thermosettable adhesive is comprised of at least one polyol such as a polyether polyol, at least one epoxy resin, and at least one polyisocyanate.

Assignee:

Henkel Corporation - Gulph Mills PA

International Classification:

US Classification:

264 453, 264 464, 264 466, 264 53, 264 54, 2642711, 264DIG 6

Abstract:

A high performance structural foam is used for stiffening parts such as plastic parts. The foam could be formulated for in-mold use at elevated temperatures or at ambient temperatures for use with previously molded parts. Various ingredients are used to control the properties of the foam.

Assignee:

Henkel Corporation - Gulph Mills PA

International Classification:

C08J 906

US Classification:

521 85

Abstract:

Titanates and zirconates bearing organic substituents can act as corrosion inhibitors when added to foamable compositions based on thermosettable synthetic resins such as epoxy resins. Combinations of organometallates containing certain specific types of substituents provide synergistic improvements in the properties of structural reinforcement foams obtained by heating and curing the foamable compositions.
