Specifications


 

Product description:

 

Construction: 3-layer system

First layer: Liquid epoxy primer, solvent-free two-component.

Second layer: High shear strength hot-melt copolymer adhesive.

Third layer: Radiation cross-linked, high density polyethylene backing.

 

Installation:

during installation, the epoxy primer is applied to the prepared pipe surface and the heat-shrinkable sleeve is immediately wrapped around the joint over the wet epoxy. Heat is then Applied to the sleeve which shrinks to form a tight fit around the joint. while curing, the epoxy forms strong mechanical and chemical bonds to the pipe surface & to the Copolymer adhesive layer. the radiation cross-linked outer layer forms a tough barrier against mechanical damage and moisture transmission.

 

Product features/benefits:

 

? Excellent multifunctional adhesive allows for lower installation pre-heat temperature and super bonding to PE, PP and 

FBE, offer fully resistant to shear forces induced by soil and thermal movements.
?Superior cathodic disbondment and hot water immersion resistance offers the optimum barrier long-term protection against corrosion.    
? Saves time & cost by lower preheat temperature, wet epoxy primer application.

Ordering information:

WSS type products are Available:

?as cut piece (pre-cut sleeve with separate closure patch)

?as a roll (closure patches to be ordered separately)

?Select sleeve width that will overlap onto the mill-applied coating by 2 inches (50 mm) minimum on each side of the weld joint. Take a 10% shrinkage during installation of sleeve width into account when calculating the minimum sleeve width.

?Sleeve cut lengths and appropriate closure patch widths depend on the pipe size and product construction, see application table.
