| 摘要 |
A polymeric article, at least part of which is dimensionally-recoverable, preferably heat-recoverable, has, bonded to the surface of a dimensionally-recoverable portion thereof, a pliant, adhesive-receptive polymeric film which is soft at the temperature at which the dimensionally-recoverable portion is recovered, and which is substantially non-curable at ambient temperatures. The polymeric film is preferably based on a film-forming chlorinated resin or a film forming silane. The articles may be recovered over objects such as electrical equipment to provide electrical insulation and may be bonded to the object or other article with an adhesive without the necessity of any special surface treatment immediately before bonding. |
