MATERIALS COMPAIBILITY

Metals

Opteon™ SF33 is compatible with most metals. Exposures to stainless steel, copper, brass, and aluminum at 100 °C (212 °F) for 2 weeks showed good stability as summarized below. Opteon™ SF33 is not compatible with strong bases; therefore, contact with highly basic process materials is not recommended. Contact with strong Lewis acids, such as aluminum trichloride, alkali and alkaline earth metals, powdered metals, and powdered metal salts, is also not recommended.

Plastics:

Opteon™ SF33 is compatible with most plastics. Exposures to most plastics at room temperature for 2 weeks showed good compatibility. Consult with your local Chemours specialty fluids representative to help answer questions about specific materials compatibility in your application.

Elastomers:

Exposures to most elastomers at room temperature for 2 weeks show compatibility. Some reversible swelling is expected with partially fluorinated elastomers. Consult with your local Chemours specialty fluids representative to help answer questions about specific materials compatibility in your application.

STORAGE & HANDLING

Opteon™ SF33 is thermally stable and does not oxidize or degrade during storage. It exhibits no closed or open cup flash point and is not classified as a flammable liquid by NFPA or DOT. Store in a clean, dry area; protect from freezing temperatures; and don’t allow stored product to exceed 46 °C (115 °F) to prevent leakage or potential rupture from pressure and expansion. Drum pumps are recommended to dispense fluid from its container. Vapor degreasing equipment with vapor containment technology are required to enable safe and economical use of the solvent. The fluid is a pure component material and easily recoverable by off-line and in-line distillation equipment, such as a vapor degreaser. Spent solvent that cannot be recycled should be tested to ensure proper classification for waste disposal. Additional safety information can be found in the Safety Data Sheet (SDS).
