Product Description
3PE Heat Shrink Wrap around Sleeves with Separate Closure for Pipes Anti-corrosion and Sealing
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.
