Opteon SF33 | Specialty Cleaning Fluid
Opteon™ SF33 is an ecologically friendly nonflammable fluid that is commonly used as a specialty cleaning or carrier fluid. Opteon™ SF33 is optimized to replace much more harmful chemicals such as HCFCs, PFPEs, HFCs, HFEs and others as an industrial solvent carrier fluid. Other applications Opteon™ SF33 is commonly utilized in the military, aerospace, and semiconductor manufacturing industries such as:
- Metal degreasing and rinsing agent
- Electronic and precision cleaning
- Ideal for: aerosol solvent/formulations, carrier fluid, and lubricant deposition
- Ultra Low GWP (≤ 2.0), zero ODP, 100% non-flammable
Opteon SF33 | Specialty Cleaning Fluid
Next-Generation HFO-Chemistry, Ecologically Friendly Carrier and Cleaning Fluid, Ultra low GWP
Opteon SF33 is a proprietary hydrofluoroolefin (HFO) specialty fluid that boast environmentally friendliness with zero ozone depletion potential (ODP) and ultra-low global warming potential (GWP) of 2. By using it customers can decrease their environmental footprint and replace much more harmful chemicals like: PFCs, HCFCs, PFPEs, HFCs, HFEs without sacrificing performance in most applications. Opteon SF33 is a proprietary HFO (hydrofluoroolefin) molecule used as the foundation to make a next generation line of ultra low global warming potential specialty fluids such as the: Opteon SF01, SF05, SF30, SF79, and SF80. Opteon™ specialty fluids are nonflammable, thermally stable, low toxicity, clear, colorless specialty fluid most commonly used as described below:
- Carrier fluid for industrial solvents
- Metal degreasing, electronics cleaning, precision cleaning, and rinsing agent
- Heat transfer fluid
- Aerosol solvent/formulations
Metal compatibility of Opteon SF33:
Opteon SF33 is compatible with most metals such as brass, copper, stainless steel, aluminum, and carbon steel. However, it is not compatible or recommended to be used with strong bases and highly basic process materials. It is also not recommended to be utilized with strong Lewis acids such as aluminum tricholride, alkali and alkaline earth metals, powdered metals, and powder metal salts.
Plastics and Elastomers Compatibility:
Opteon™ SF33 showed good compatibility with most plastics and elastomers after being tested at room temperature for 2 weeks. Please refer to charts under “Technical Data” or contact our technical support team for questions regarding specific materials compatibility in your application.
Storage and handling for Opteon SF33
Opteon SF33 exhibits no closed or open cup flashpoint and not classified as a flammable liquid by the NFPA or DOT. It is thermally stable and does not oxidize or degrade during storage. Store in a clean and dry area that is protected from freezing temperature but also does not exceed 46C to prevent leakage or potential rupture from pressure and expansion. Drum pumps are recommended to dispense fluid from its container. Those vapor degreasing companies that utilize vapor containment technology must enable safe and economical use of the Opteon SF33 solvent. It is easily recoverable by off-line and in-line distillation equipment, such as vapor degreasers since it is a pure component material. Always be sure to test for proper waste disposal classification for solvent that cannot be recycled. Safety data sheet (SDS) is available for those who need additional and more in depth safety information.
