Opteon™ SF05
Specialty Fluid

Removes Fine Particulate and Ionic Soils

Technical Information
Introduction• No surfactants needed: Removes extra washing steps toachieve residue-free cleaning

Opteon™ SF05 is a proprietary specialty solvent blend
based on Opteon™ hydrofluoroolefin (HFO) and ethanol. It is
intended for use in removal of fine particulate and ionicsoils from component parts. It offers improved solvency for• Low odor and toxicity• Excellent environmental profile: Low GWP (<10), EU 517/
2014 compliant

polar soils, while maintaining excellent compatibility withmost plastic, ceramic, and metal components. Typicalapplications include sub-micron size complementary

Typical Applications

metal-oxide-semiconductor (CMOS) particle removal,• Sub-micron CMOS particle removal and sensor cleaning

precision cleaning, and removal of light soils from metal,• Light oil and grease removal

plastic, and glass substrates. Opteon™ SF05 is a safe,
nonflammable, and environmentally friendly solvent withlow global warming potential (GWP) (<10) and does notcontain any fluorinated greenhouse gases (as listed inAnnex 1 of the EU regulations 517/2014). Opteon™ SF05
is intended to replace high global warming hydrofluorocarbon(HFC)- and hydrofluoroether (HFE)-based cleaning solvents,
as well as high ozone depletion potential (ODP) CFC-113,HCFC-141b, HCFC-225, and 1,1,1-trichloroethane
solvents in many industrial applications.

Contaminants, such as dust particles, skin flakes, fibers, andother process contaminants, tend to bond with the surfaces

Removal of these contaminants requires a solvent that canreduce the laminar boundary layer thickness to allow particles
to be washed away by the liquid solvent flow-through.
A thin boundary layer and higher liquid flow-throughmomentum can be accomplished with a cleaning fluid, suchas Opteon™ SF05, which has a high density, low viscosity,and low surface tension, so that fine particles can be
