ZBL-RP
Repair Patch
ZBL-RP repair patch is a heat-applied patch which, in combination with mastic filler, offers an economically effective and high quality repair system for factory PE pipe coatings damaged mechanically during transportation, storage and laying of pipes. It’s designed to repair the damage areas on line coatings, mainly 2 or 3 layer PE.
Construction: Two-layer or three-layer system:
• First layer: Liquid epoxy, solvent-free two-component (optional)
• Second layer: Copolymer adhesive
• Third layer: Radiation cross-linked, unexpanded polyethylene
Installation is done with standard gas torches. To repair a damaged area, installers round out, roughen, clean and preheat the area and positioned onto the treated area and heated. During heating, the adhesive softens and flows to form a tight bond with the substrate. The bond strength builds up during cool-down and is fully retained after job completion.
Features:
• Adaptable repair system.
• Resistant to high shear forces.
• Excellent adhesion to commercial, PE mill-applied coatings.
• No special equipment required.
Benefits:
• Long lasting and high performance.
• Saves time with fast and convenient installation.
• Saves money by keeping inventory and logistics costs low.
• Makes installation fast and easy. Keeps installation costs low.
