RUST BITES
PIPELINES
RESTORED. PROTECTED.
CORROSION
COSTLY LEAKS
SHUTDOWNS
ACCIDENTS
CORROSION EATS THE PIPE WALL.
REPAINTING OVER RUST IN PITS HIDES THE NEXT FAILURE.
REPAIR. CONVERT. PROTECT.
FILL LOCAL PITS.
RESTORE THE
PROFILE.
Z801 FASTSTEEL
Fast-setting, steel-filled
repair for approved local
pits.
CONVERT RUST.
BOND THE TOPCOAT.
Z704 RUSTEX-NMB
Converts residual rust.
Treats salt and acid traces.
COAT THE PIPE.
SHIELD THE STEEL.
SELECTED TOPCOAT
External protection from
moisture, salt, acid
exposure and dirt.
01
WHY Z704 IS FIRST IN THE WORLD
TRIARMOR TECHNOLOGY
WORLD'S FIRST MULTI-CHEMISTRY,
NANO-MOLECULAR ADHESION RUST CONVERTER
CONVERTS DEEP RUST
Converts residual rust
inside prepared pits.
TREATS RESIDUAL
TRACES
After washing, treats rust
beneath salt/acid traces
and seals the interface.
BUILDS COVALENT
BOND
Bonds converted steel to
the protective topcoat.

02
WHY REPAINTING FAILS
PITTING EATS
THE PIPE WALL.
Rust, moisture, salt and
acid remain trapped in
pits.
Z801 | RESTORE LOST
PROFILE
RUST REMAINS
WHERE TOOLS
CANNOT REACH.
Between pipes.
Under clamps.
Around supports.
Z704 | CONVERT WHAT
REMAINS
PAINT PEELS.
RUST GROWS
BELOW.
Weak rust causes poor
adhesion and blistering.

WHERE CORROSION COSTS
COOLING-TOWER LINES
WET SUPPORTS.
RUST RETURNS.
Flanges. Low points.
Repainting costs.
FIRE-HYDRANT LINES
FIRE LINES
MUST WORK.
Corrosion threatens
emergency water supply.
ACID EXPOSURE | PICKLING PLANTS
ACID FUMES + SPLASHES.
PIPE EXTERIORS CORRODE.
Acid residues stay active in pits.
SALT EXPOSURE | COASTAL SITES
SALT-LADEN AIR.
PIPE EXTERIORS CORRODE.
Salt in pits sustains corrosion.
MECHANICAL SURFACE
PREPARATION NOT PERMITTED
NO BLASTING.
NO GRINDING.
NO HOT WORK.
Clean first.
Convert residual rust.
ELEVATED PIPE RACKS
DIFFICULT ACCESS.
REPAINTING MEANS
SCAFFOLDING AGAIN.
Overhead pipes.
Joints. Supports.

ENGINEERING CHECK
Z801: Assess wall thickness and fitness first. Approved local pits only.
Z704: Remove loose scale, oil and contamination; wash salts first. Maximum 70°C.
Confirm topcoat compatibility, layer order, film build and cure before application.
DON'T OVERPAINT RUST.
REPAIR. CONVERT. PROTECT.
HELPS PREVENT LEAKS FROM EXTERNAL CORROSION.
