Abstract:
Novel curable adhesives are solid, substantially free of cross-linking and substantially tack-free at 25. degree. C. ; remain substantially uncured when maintained for extended periods at 80. degree. C. ; have an initial viscosity of 10. sup. 3 to 10. sup. 4 poise at 150. degree. C. and cure relatively slowly at 150. degree. C. ; and cure rapidly at 200. degree. C. The adhesives preferably contain at least one epoxy resin, particularly an epoxy resin having a softening point of at least 50. degree. C. and an epoxy equivalent weight of at least 200 in combination with an epoxy resin which is liquid at 25. degree. C. or an elastomer or other compatible high molecular weight polymer. The adhesive preferably also contains a high temperature curing agent and preferably also a filler, which may be particulate or fibrous. The novel adhesives are particularly useful in combination with heat-recoverable devices, e. g. devices comprising components made of heat-recoverable metal.

Abstract:
The ends of heat-recoverable polymeric sheet material are joined by overlapping the ends and bonding them together by means of a laminar panel comprising a layer of a crosslinked hot-melt adhesive coated on one surface of a reinforced polymer layer. The panel has a width approximately that of the sheet material being joined. The panel is disposed, adhesive side down, so that approximately half of its adhesive coated surface contacts the sheet material on either side of the line defined by the uppermost of the overlapping ends. The panel is heated to activate the adhesive and form a secure bond joining the ends. Heat-recoverable sleeves can be made by joining the opposing ends of a single length of heat-recoverable sheet material.
