Opteon™ SF79 cleaning agent

Opteon™ SF79 (previously called Sion™) is a high solvency cleaning agent developed to replace nPB and in response to worldwide market demand for safe, nonflammable and low environmental impact products for cleaning applications. Typical applications for this product include degreasing, precision cleaning, defluxing, silicone removal, and general solvent cleaning.



♦ Designed to clean a wide range of soils

♦ Fast, residue-free drying; offers viscosity to clean oil and grease from small parts, leaving no residue

♦ Compatible with a broad range of metals, plastics, and elastomers

♦ Chemically and thermally stable

♦ Zero ODP and low GWP (< 15 GWP)

♦ Recyclable and reusable

♦ Low surface tensions

♦ Nonflammable

♦ Allows for the continued use of existing equipment (no or minimal equipment upgrade necessary)

♦ Easy to handle, easy to store

♦ Also available in pails and drums. Call for pricing.

Opteon™ SF79 represents a safe alternative to chlorinated solvents such as HCFC-225, 141b, TCE and nPB, which are currently being phased out due to health and environmental risks. The safe exposure limit for nPB has been measured at 5-10 ppm – industry authorities even recommend further reducing to 0.1 ppm – whereas Opteon™ SF79 has a safe exposure limit of 201 ppm, which is comparable to everyday rubbing alcohol.


The cleaning power of Opteon™  SF79 has been measured up to a 100 KB value, which is a cleaning power standard. Opteon™ SF79 can match nPB and other common formulations ounce for ounce, providing all their solvency benefits, while offering a superior toxicity profile.


While Opteon™ SF79 is a safe, effective, and environmentally friendly nPB replacement, nPB requires acid acceptance testing, stabilizer maintenance, and solvent air monitoring for safe and effective use. These additional formulations and processes increase your overall cost of using nPB – making Opteon™ SF-79 an even better, safer value.
