About us

A new laminated zinc tape to protect buried iron and steel pipelines and pipework has been introduced by BAC Corrosion Control, Telford, a leading specialist in corrosion protection.  

ISOZIN laminated zinc tape comprises a layer of 99.99% 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.  

Feature 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 corrosion protection system is designed to be applied to uncoated, mainly above ground iron and steel surfaces to provide protection for the lifetime of the pipe and virtually eliminate maintenance re-painting costs.  

The laminated zinc tape can be applied manually or by machine for larger components.
