The Onstream Group and Oxifree Global join efforts to provide practical long-term corrosion and contamination control to a wide range of Complicated Industrial metallic structures.

What is Oxifree?

Oxifree TM198 is a sprayable polymeric resin coating for the protection of metallic components. It contains organic corrosion inhibitors, is reusable and provides protection against all corrosive contaminants with the key commercial advantage of remaining extremely easy to apply and reuse. In addition Oxifree TM198 contains under 0.5% Volatile Organic Compounds(VOCs) therefore has no adverse ecological or environmental impact. When applied by a simple heated application machine it provides a pliable polymeric barrier coating, which will protect all types of metal components against galvanic pitting and atmospheric corrosion. Oxifree is designed to create a barrier for a range of vulnerable equipment and components from water and dust ingress. It is ideal for flanges and valves on process piping, and long term storage of equipment in normal atmospheric conditions, with a key commercial differentiator of being reusable.

Asset Integrity

The application machines have undergone extensive development and testing and come in 2 different sizes: 12lbs/5.5kg and 50lbs/22kg to cater for a total range of application criteria.


Oxifree material has been thoroughly tested to 11,688 hours of "industry standard" Salt Spray test, which complies with ASTM B117 corrosion testing which is equivalent to in excess of 50 years ‘in the field'. Oxifree has also been through ASTM G56 UV/Weathering test and again exceeded required longevity with ease:

  • ASTM B117 – Salt spray test – successfully tested to 4x industry benchmark
  • ASTM G154 UV – Weathering test successfully exceeded standards
  • GOL492/09 Volatile Organic Compound Test ( <0.05%)
  • Boeing BSS 7239 – Successful smoke toxicity test
  • ASTM E662 – Successful smoke generation test
  • ASTM G85-94 – Annex A5 prohesion test – successfully approved with 1000hrs testing
  • BS EN 13823 – Single burning item test – Complete and passed within standards
  • ASTM D790 – Cryogenic bend flexibility
  • ASTM D149 – Dielectric strength testing
  • BS2782 Pt.2 – Volumetric resistivity testing (Electrical resistance)
  • ASTM D7359 – 13 Standard Test Method for Total Fluorine, Chlorine and Sulfur in Aromatic Hydrocarbons
  • ASTM E968 – Sand abrasion resistance
