• 99.99% pure zinc
• 80 microns nominal thickness
• Supplied with 25 microns adhesive (electro-conductive)
• Which can stand continuous operation temperature of 80°C
• "Zinc Tape" is designed to cover the surface of iron, steel, aluminium and light metals in order to protect the from corrosion.
• Achieved by pressing the Zinc Tape on the surface that needs to be protected from corrosion.
This method is commonly known as "COATING WITH A ZINC LAYER".







TECHNICAL DESCRIPTION

  • Zinc Tape thickness always remain the same
  • Zinc granules dispersed evenly throughout the entire electro-conductive adhesive layer
  • The granules enable the adhesive layer to be electro-conductive, thus ensure metallic contact



Zinc Tape is a product that grants natural protection
Another Important Function of Zinc Tape
• Zinc Tape protects against corrosion in an active way.
• Prevent galvanic corrosion.
• Zinc Tape sacrifies itself to protect the underneath structure.
• Acts as sacrificial anode between light metals & steel.

Resume Features
• Passive protection (like standard coating system)
• Active protection (cathodic protection effect)
• Homogeneous and isotropic structure (no problem with sharp edges / angle)
• Ecological coating (environmental friendly)
• Requires no superior surface preparation (St3)
• Allows for its application at any time during the life-span of the structure
• Enables any existing coating to be repaired or reconditioned
• Ensures a much longer life-span than that of hot-dip galvanizing or other zinc coatings of the same mean thickness.
• Easily shop-applied onto single pieces
• Can be applied in multiple layers, when extra-thick coating is required
• Can be subsequently painted
• Special coating can be taylor made to order
