Abstract

See full text

A self-heating sealant or adhesive may be formed using multi-compartment microcapsules dispersed within a sealant or adhesive. The multi-compartment microcapsules produce heat when subjected to a stimulus (e.g., a compressive force, a magnetic field, or combinations thereof). In some embodiments, the multi-compartment microcapsules have first and second compartments separated by an isolating structure adapted to rupture in response to the stimulus, wherein the first and second compartments contain reactants that come in contact and react to produce heat when the isolating structure ruptures. In some embodiments, the multi-compartment microcapsules are shell-in-shell microcapsules each having an inner shell contained within an outer shell, wherein the inner shell defines the isolating structure and the outer shell does not allow the heat-generating chemistry to escape the microcapsule upon rupture of the inner shell.
