Did you know that VISCOTAQ™ is an ideal solution for protecting buried stainless steel?

While stainless steel is naturally resistant to rust, its smooth, low-porosity surface still presents challenges for coatings…

VISCOTAQ’s viscoelastic composition ensures it bonds securely to stainless steel surfaces, creating a seamless barrier that prevents air gaps or vulnerabilities (even on irregular shapes or complex geometries).

This was demonstrated during a May 2023 project at the new Sydney Airport, where VISCOTAQ™ ViscoWrap HT (thermal resistance from -45°C to 95°C) and VISCOTAQ™ PVC Outerwrap were selected as a two-layer coating system to provide long-term protection for a buried stainless steel fuel piping network.

The project wrapped nearly 50 stainless steel spools, each with a 2–3” diameter, designed as part of a more extensive fuel piping system. These spools were wrapped off-site before being transported to the project location, where the final welding and protection of the field joints was completed.

Key to the project’s success was the specialised training provided by our National VISCOTAQ™ Manager, Adam Matthews. This training ensured the applicators were well-versed in proper surface preparation and the correct application methods, all of which contributed to an excellent outcome.
