Frequently Asked Questions
How does zinc tape prevent corrosion?
Zinc tape uses a zinc-rich adhesive layer that acts as a sacrificial anode, so it corrodes in place of the conductive metal underneath. This provides galvanic protection to scratches, cuts, and exposed areas.
Can this tape be used underwater?
Yes, it is designed for marine environments and can be applied to submerged surfaces. However, the surface must be properly prepared and the tape fully pressed down to ensure a watertight seal.
Which surfaces can it be applied to?
It is suitable for steel, stainless steel, aluminum, brass, and copper. Do not use on painted surfaces unless the paint is removed, as the adhesive needs a clean conductive surface to work effectively.
How should the tape be stored?
Store in a cool, dry place at ideally 15–25°C. Avoid prolonged exposure to direct sunlight or high humidity, and keep the roll in its original packaging until use.
