ABSTRACT:
A dimensionally heat-recoverable article has on one of its surfaces a heat-curable adhesive coating. The coating has a mixture of substantially solid particles of a first reactive component with separate substantially solid particles of at least a second reactive component, the first and second components being capable of reacting together to effect curing of the coating when the heat-recoverable article is heated to its recovery temperature. The particles have a size distribution in which not more than 40% by weight of the particles are less than 50 micrometers in size and at least 90% by weight of the particles are less than 300 micrometers in size.
