Oxifree TM198
Oxifree TM198 is a Thermoplastic coating applied in a fluid state. It can easily be removed when required and is 100% reusable. It contains organic anti-corrosion inhibitors that penetrate threaded fastenings to stop seizures.
Oxifree although looks as if it is sprayed or extruded, in reality it is actually pumped on the substrate at low pressure and forms a cocoon or encapsulation and as such does not adhere to the substrate.
The inhibitor oil constantly bleeds through the coating and creates a very fine film on the substrate which acts in several ways:
- to reverse any existing corrosion
- form a barrier to prevent air, moisture and contaminants from penetrating the coating/substrate interface
- The Thermoplastic coating also creates a substantial encapsulation - the film thickness is measured in millimetres, 4mm to be precise where paint coatings are measured in microns
Testing:
Oxifree material has been thoroughly tested to 11688 hours of industry standard "hot salt fog test", in accordance with ASTM B117 corrosion testing. This is equivalent to in excess of 20 years ‘in the field’ and significantly in excess of the industry standard 3000 hours testing which most coating companies aim to achieve for their products.
Oxifree TM198 has also been put through ASTM G154, accelerated UV and weathering test. Oxifree went to the maximum 400hrs without any degradation.
Oxifree TM198 has been tested for content of volatile organic compounds (“VOC´s”) and has been found to have 0- 0.05% content making it exceptionally ecologically friendly and safe to use or apply.
Recommended Use:
- Anti-corrosion protective coating applied to bolted flanges, valves bearing housings, critical pipeline connections, short and long term storage of strategic machine parts and metal surfaces regardless of size or shape that are exposed to aggressive/corrosive working and storage environments.
- Prevention of the ingress of fluids and solids into bearing houses, gear boxes, electrical motors for example.
- Metal interfaces composed of different materials and metal surfaces affected by corrosion caused by exposure to chemical and maritime environments.
- Protection of mobile machinery and components, in short or long term storage.
- The flexible polymeric resin coating allows for easy removal for inspection and re-application during scheduled maintenance.
Hazardous Ingredients/Identity:
- Proprietary ingredients
- Chemical Family: Cellulose
- Contains no known hazardous components as defined in Standard 29 CFR 1910.1200
Appearance:
Standard grey, semi-gloss surface or other colours on request.
Melting point:
120C / 248F
Recommended application temperature:
165 to 175C / 329 to 347F (operating temperature should not exceed this)
Resistance:
Will resist a wide range of physical metal reactions inclusive of chemical splashing and sea water/spray.
Chemical definition:
100% solids
Application:
By a choice of 3 portable Polymelt units to heat and apply the Oxifree TM198
1. Polymelt 12 (12lb / 5.5KG capacity) machine which is lightweight and offers ease of transportation for
smaller applications
2. Polymelt 50 and Polymelt 50 ATEX2-22 (50lb / 22KG capacity) machines for greater levels of sustained working application and for use in hazardous environments
Surface preparation:
- A general commercial clean to remove loose and flaking fragments of existing coatings and rust.
- Follow with a solvent wash with water to remove any oily surface contaminants.
- Dry the surface before applying the Oxifree material
Recommended application thickness:
- 4.0mm for protection on the spot/site
- 2.0mm for protection of parts in stock
Time to dry:
- Varies depending on ambient conditions and surface temperature, but no more than:
- Touch dry: 3-5 minutes
- Overlay: 5-10 minutes
- General handling: 15 minutes (to avoid skin burns)
Applying in adverse conditions:
- Exposure to extreme temperatures and UV may induce the appearance of rust inhibiting agents on the surface of the coating resulting in a slight change of appearance; however this does not affect the preventive corrosion characteristics.
- Applications in temperatures below -15C / 5F that are free of ice and moisture will require a continuous application process.
- Maximum temperature of the surface for application: 90C / 194F
- Environments with temperatures around or below -25C/-13F may need special Oxifree additives.
Fire and Explosion Hazard Information:
- Extinguishing Media- Water vapour, Dry chemical, Foam and CO2
- Treat as oil fire
- Vapours possibly flammable beyond 220 ̊c/428 ̊f flash point
Storage and Handling:
- Store in cool dry environment (below 27 ̊c/80 ̊f)
- Waste Disposal as per local legislation same as wax or vegetable oil
Safe handling during application:
- Wear protective gloves while handling hot material
- Wear eye protection while handling hot material
