摘要 |
A recoverable polymeric material is coated with discrete regions of a sealant, such as a mastic, and of a heat-activatable adhesive, such as a hot-melt adhesive. The coated material forms a sleeve which may be of tubular or wrap-around configuration. The sleeve may be used to cover weld joints in polyethylene coated steel pipes. The sealant ensures a flexible water-proof seal around the weld and the adhesive provides a second seal and prevents any long range movement between the sleeve and the pipe. |
