1 EVAPO-RUSTEvapo-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.
2 EVAPO-RUST INNOVATIVE TECHNOLOGY WINNER - R&D’s “TOP 100 INVENTIONS AWARD ”WINNER - CleanTech’s “Outstanding Technology in Industrial Cleaning ”NO LABOR * NO ACIDS/CAUSTICS * SAFE ON SKIN!UNIQUE - Works by Selective Chelation at pH (neutral)REPLACES Acids, Caustics, Electrolysis, Even Media BlastingNO Health or Environmental HazardsFEATURE of dozens of articles in trade publications spanning the Automotive, Marine, RV, and Manufacturing Industries.
3 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.
4 COMPLETELY IMMERSE ITEM HOW TO USE EVAPO-RUSTPictures from SIMA-San Diego Naval FacilityCOMPLETELY IMMERSE ITEMEVAPO-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.
5 Evapo-Rust Health & Environmental Analytical PH 6.1Non-HazardousNo VOC - NO HAPNon-Corrosive (NACE TH0169 = <6.35 mm/yr)Not Orally Toxic (LD50 >5g/kg)Not Dermally Toxic (LD50 >2000mg/kg)Not an eye irritant (MMTS = 0.0)Not a skin irritant (PDII = 0.9)Spent material is Non-HazardousRemoves rust by Selective ChelationNo DOT Restrictions
6 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.
7 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 platingEvapo-Rust does not affect non-oxide paintsEvapo-Rust works best above 60 FEvapo-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™
