Patent ID: 8043460

Claim:
An elastomeric epoxy dry adhesive composition comprising: at least one of a rigid epoxy or a flexible epoxy; and at least one of a crosslinking agent or a catalytic curing agent; at least one of an epoxy extender having, one epoxide group, or a diluent comprising a monoamine or a mono-carboxylic acid; wherein the rigid epoxy is an aromatic epoxy having at least two epoxide groups, the flexible epoxy is an aliphatic epoxy having at least two epoxide groups, and the crosslinking agent comprising at least one of a multi-amine, an organic multi-carboxylic acid, or an anhydride; and wherein the components are present in an amount sufficient to provide, upon curing of the composition, an elastomeric epoxy dry adhesive having a glass transition temperature below room temperature and having a pull-off strength of 1-200 N/cm 2 from a substrate; and when the crosslinking comprises a multi-amine the total number of epoxy groups to amine groups ranges from 1.89-2.12.
