FRDP heat shrinkable sleeve HSS bonds the steel substrate, FBE primer and plant-applied polyethylene coatings excellently to form a continuous and durable corrosion protection system on the pipeline.
The heat shrinkable sleeve system consists of a two-component solvent-free epoxy primer, a heat-recoverable radiation cross-linked polyethylene backing coated with a hot-melt adhesive layer and a closure patch.
FRDP 60C heat shrinkable sleeve can be used as either 2-layer or 3-layer sleeve system. It depends on whether liquid epoxy primer is needed or not. For added flexibility, the sleeve can be supplied as bulk rolls or pre-cut to the required pipe size.
