A new laminated zinc tape that reportedly eliminates risks of corrosion of steel underneath rubber window seals for the transport and automotive industries has been introduced by BAC Corrosion Control, Tetford, a specialist in corrosion protection. Typical applications are thought to be railway carriages, trams, buses and coaches, commercial vehicle cabs and the automotive industry generally.
ISOZIN laminated zinc tape comprises a layer of 99.99 per cent pure zinc 80 microns (0.08mm) thick with 25 microns (0.025mm) of adhesive protected by a removable siliconised paper. It is available in 50-metre long rolls in widths ranging from 10mm up to 300mm.
A feature claimed of the new laminated zinc tape is its electrically conductive adhesive, which, as well as securing the tape to the steel substrate, ensures a positive electrical connection to the zinc so that it can act as a sacrificial galvanic anode. This is achieved by incorporating a percentage of powdered zinc into the adhesive during manufacture.
The product is said to be designed to cover unpainted iron, steel and aluminium alloys to provide local corrosion protection that, in most cases, will last longer than the life of the structure being protected. To prevent galvanic action between dissimilar metals in the presence of moisture, tape can be applied to the more noble of the two to lower the potential difference between the two surfaces.
