System  Description


Hot Melt Polyethylene Anti-corrosion Tape is a wrap around radiation cross linked tape designed for corrosion protection of straight pipes, fittings, bends, elbows and other irregular configurations. When heated the backing layer shrinks and the adhesive flows and forms a reliable corrosion protection seal onto metal and adjacent coating surfaces.


The epoxy primer should applied to the prepared pipe surface then heat shrinkable tape is immediately wrapped around the joint over the wet epoxy.


Then center the closure patch on the overlap region.


Product  Composition


The pipeline heat shrink tape consists of three layers, primer layer, adhesive layer, film backing.

Primer: Liquid epoxy,  solvent free two component.

Adhesive: High shear strength copolymer adhesive

Film backing: Radiation cross linked. High density polyethylene 


Product  Features
