An adhesive composition ('composition') comprises an epoxy resin, a binder, and a curing agent. Typically, the composition further comprises an aqueous solvent (e.g. water) such that the composition can be referred to as an aqueous adhesive composition. The epoxy resin is typically encapsulated to prevent premature cure of the composition. After rupture of the encapsulated epoxy resin, the composition cures to form an adhesive. The composition is useful for articles such as fasteners (e.g. nuts and bolts) such that it can be referred to as a fastener adhesive. Typically, the composition is disposed on a threaded surface of the fastener. The fastener can be used for an assembly in which the composition generally cures after installation of the fastener. To make the fastener, the adhesive composition can be applied on the threaded surface. After application, the composition can be dried in instances where the composition still includes the aqueous solvent.

Adhesive composition and article including the same

A method for microencapsulating a core material, such as a blowing agent, in a single shell which has demonstrated to be challenging to microencapsulate as an individual component with a single-shell wall deposition using conventional techniques. Single-shell microcapsules of the blowing agent can be formed, minimizing steps involved in the present microencapsulation technique. Also, microcapsules formed by this method provide increased performance in end-use products, including but not limited to characteristics such as product shelf-life, ease of use, and greater expansion properties. A method of making a coating formulation including the microcapsules is further provided, as well as a fastener including the coating.

A coating composition adapted for application on a fastener, the coating composition composed of a binder component composed of a polymeric resin present in the composition at a concentration between 1.0% and 15.0% by total composition weight, wherein the binder component is composed of at least one of a solvent dispersible compound; a reactive cross-linking component present in the composition in an amount between 1.0% and 80.0%; at least one curing agent; optionally at least one expansion agent, wherein at least one of the curing agent or the reactive cross-linking component are physically and reactively isolated from other components of the composition.
