Opteon™ SF33

Specialty Fluid

Storage and HandlingOpteon™ 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 byNFPA or DOT. Store in a clean, dry area; protect fromfreezing temperatures; and don’t allow stored product toexceed 46 °C (115 °F) to prevent leakage or potential
rupture from pressure and expansion. Drum pumps arerecommended to dispense fluid from its container. Vapor
degreasing equipment with vapor containment technology
are required to enable safe and economical use of thesolvent. 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 berecycled should be tested to ensure proper classification
for waste disposal. Additional safety information can befound in the Safety Data Sheet (SDS).
