Comparison of Anti-Corrosion Methods: AS66 NoRUST ActiveShield Tape vs. Other Techniques

The AS66 NoRUST ActiveShield Tape is a comprehensive anti-corrosion solution designed to provide long-lasting protection across a variety of industrial applications. The tape is composed of a zinc layer with electro-conductive adhesive for active protection and a bituminous membrane with an HDPE film offering passive protection. This dual-layer structure enhances the tape’s resistance to moisture and mechanical damage, ensuring the zinc layer remains intact and effective over the years.

The below analysis evaluates the efficacy, advantages and disadvantages of AS66 Tape against various conventional anti-corrosion methods.

Method
VCI
(Volatile Corrosion Inhibitors)
Mechanism
Emits vapours that prevent corrosion
Pros
- Non-intrusive
- Effective in enclosed spaces

Cons
- Limited duration
- Requires sealed environment

Comparison with AS66
- AS66 provides long-term protection in open and harsh environments
- No need for sealed conditions
Method
Environmental Control
(e.g. dehumidification)
Mechanism
Controls environment to reduce corrosion risk
Pros
Effective in controlled environments
Cons
- Energy-intensive
- Costly
- No active protection
Comparison with AS66
- AS66 is more cost-effective in long term
- Provides active protection in any environment
