EVAPO-RUST

1
EVAPO-RUST

• Evapo-Rust is a patent pending non-hazardous
  rust remover that employs a unique selective
  chelating agent to remove rust (iron oxide)
  without posing any health or environmental
  hazards.

HOW TO USE EVAPO-RUST

• 4-PREPARATION (suggestions for best results)
• CLEAN RINSE THE ITEM PRIOR TO DE-RUSTING
• (Item should be free of mud, dirt, loose rust,
  oil, and grease.)
• WHY?
• 1.) EVAPO-RUST DOES CONTAIN A SURFACTANT TO HELP
  IT OVERCOME DIRT, OIL, AND SOME GREASES.
  HOWEVER, EVAPO-RUST IS A RUST REMOVER, NOT A
  CLEANER AND THE PERFORMANCE MAY BE AFFECTED,
  ESPECIALLY FROM GREASES.
• 2.) EVAPO-RUST IS SEWERABLE AS SUPPLIED. ADDING
  OILS AND GREASES MAY CHANGE THE STATUS OF THE
  DISPOSAL. IF YOU ARE ONLY DE-RUSTING CLEAN
  STEEL, ALL THAT REMAINS IS CHELATED IRON AND
  WATER. IN MOST CASES, ONLY THE IRON CONTENT
  SHOULD DICTATE THE DISPOSAL REQUIREMENTS. (check
  local restrictions and dispose of according to
  local, state, and federal guidelines.
• 3) RINSING ASSURES YOU WILL NOT BE DRAGGING
  OTHER CLEANERS INTO THE EVAPO-RUST SOLUTION.
  RAISING THE pH OF EVAPO-RUST WITH OTHER CHEMICALS
  CAN RENDER THE SOLUTION USELESS.

HOW TO USE EVAPO-RUST
Pictures from SIMA-San Diego Naval Facility

• COMPLETELY IMMERSE ITEM
• EVAPO-RUST is easy to use. Fully immerse the
  rusted item in EVAPO-RUST and check progress in
  about 30 minutes no scrubbing necessary. Soak
  times will vary from 30 minutes to 24 hours
  depending on severity of rust, type of steel, and
  temperature. EVAPO-RUST is water based, therefore
  the active molecules will slow down as
  temperature decreases and increase as temperature
  increases. We recommend utilizing EVAPO-RUST at a
  bath temperature above 60 F.
• Once rust is removed, rinse item with water. You
  can now paint, plate, or apply a long term
  Corrosion Preventative Compound (CPC) such as
  Carwell CP90. For short term rust inhibition,
  simply dip the item in EVAPO-RUST and allow to
  dry. Rinse with water before painting, plating
  or applying a CPC.

How Does Evapo-Rust Work?
EVAPO-RUST works at a pH of 6.1 to 7 (neutral)
through selective chelation. This is a process in
which a large synthetic molecule forms a bond
with metals and holds them in solution. Most
chelating agents bind many different metals. The
active ingredient in EVAPO-RUST bonds to iron
exclusively. It can remove iron from iron oxide,
but is too weak to remove iron from steel because
the iron is held much more strongly.

Limits/Advantages of Evapo-Rust

• Evapo-Rust specifically targets Iron oxide
• Evapo-Rust does not harm aluminum, brass, copper,
  plastic, rubber, silicon, wood, felt, or glass
  (de-rust without dis-mantling)
• Evapo-Rust must be used as a liquid (wet process)
• Evapo-Rust does not affect plating
• Evapo-Rust does not affect non-oxide paints
• Evapo-Rust works best above 60 F
• Evapo-Rust does remove sacrificial coatings
  such as bluing, browning, zinc, or other oxides.
• Hematite - ?  Fe2O3 and- Fe(OH)3 , Goethite are
  not affected by Evapo-Rust
