black and silver anticorrosion tape based on a double active passive protection barrier on roll

NoRust
ActiveShield Tape

An effective anti-corrosion solution providing cathodic protection, reinforced with a bituminous membrane and covered with HDPE film, designed for extreme fields of applications.

Dual Anti-Corrosion Protection

The new-generation ActiveShield anti-corrosion tape owes its effectiveness to both active and passive protection. This composite product consists of an external membrane layer that ensures tightness, and an inner layer that acts as an anode.

Active Protection 

The Active protection is achieved through the use of high-purity zinc tape with electro-conductive adhesive, ensuring excellent conductivity between the protected metal and zinc.

Zinc, being more electrochemically active than iron, acts as an effective anode when used to cover steel surfaces. This prevents the formation of small anodic and cathodic regions on the metal surface, thereby significantly reducing the development and spread of corrosion.

As a sacrificial coating, zinc always corrodes first, in contrast to other coatings like paint or aluminium, where steel corrosion can undercut the coating over time, diminishing its effectiveness.

Passive Protection

The Passive protection is provided by a bituminous membrane covered with a high-quality HDPE film. It offers excellent sealing and creates a barrier against mechanical damages, acids and moisture in the soil, preventing corrosion from occuring. Additionally, it is resistant to stretching, bending and it is waterproof.

    Installation instructions

    SURFACE PREPARATIONS

    • The surface must be dry and free from corrosion.
    • Remove all coatings covering the metal surface.
    • Surface with visible light or medium corrosion needs to be cleaned by mechanical or manual wire brushing.
    • In order to achieve an optimum functionality of tape it is important to ensure direct contact between tape and steel.

     

    TAPE APPLICATION

    • Tape is applied directly onto the steel structure.
    • During the installation, apply the tape on the whole surface, leaving no exposed metal surface.
    • To protect irregular shapes, tape needs to be cut to the required dimension.
    • Apply the tape carefully to avoid air bubbles or creases.
    • Very good adhesion is achieved by using a magnetic roller applicator.
    • The application of tape on pipes is the fastest and most efficient when carried out by a wrapping machine.

    Otherwise, tape needs to be cut and hand-applied. Tape can be pressed to the metal surface using a squeegee – this would allow to achive good connection between the tape and the metal surface.
