NoRustActiveShield 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
Passive protection is achieved through a bituminous membrane covered with a high-quality HDPE film. This structure ensures excellent sealing and creates an effective barrier against mechanical damage, acids, and soil moisture, preventing corrosion. Additionally, the material is resistant to stretching and bending and is completely waterproof.

AntiRust Tape – Installation Instructions
Surface Preparation
The surface must be dry and free from corrosion.
Remove all coatings that cover the metal surface.
Surfaces with visible light or medium corrosion should be cleaned by mechanical or manual wire brushing.
To ensure optimal functionality of the tape, it is essential to establish direct contact between the tape and the steel surface.
Tape Application
The tape is applied directly onto the steel structure.
During installation, the tape should cover the entire surface, leaving no exposed metal.
To protect irregular shapes, the tape should be cut to the required dimensions.
Apply the tape carefully to avoid air bubbles or wrinkles.
Excellent adhesion can be achieved by using a magnetic roller applicator.
For pipes, the fastest and most efficient application method is using a wrapping machine.
If a wrapping machine is not available, the tape should be cut and applied manually.
The tape can be pressed onto the metal surface using a squeegee to ensure a strong bond between the tape and the metal.
