Opteon SF79 HFO Based Next Generation Low GWP Precision Cleaning Fluid 

Opteon SF79 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, 3D metal parts cleaning (Used in MarkForged Metal X 3D printer Wash-1).  Superior cleaning performance with best solvency power in its class (Kb value = 103)

Retrofit Guidelines

Benefits

• Nonflammable

Safety

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.

Performance

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.

Maintenance

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.
