Abstract
A dimensionally recoverable article, preferably a heat-recoverable article, has on at least part of a surface thereof an adhesive composition that will cure by reaction of a plurality of mutually reactive components. The components are in the form of particles which are mixed together and which will fuse when heated. Preferred adhesives are based on combinations of an epoxy with a polyamide, carboxylic acid, phenolic resin or blocked isocyanate curing agent. The particulate adhesives show a synergistic increase in rate and/or level of cure when used in conjunction with a recoverable article.
