Next Generation Low GWP Precision Cleaning Fluid

Technical Information
Introduction

Features and Benefits

Opteon™ SF80 specialty fluid is designed to meet the high• S uperior cleaning performance with best solvency

solvency needs in the industrial cleaning market. Opteon™
SF80 is a safe, nonflammable, and environmentally friendly
solvent with low global warming potential (GWP) (<2.5) anddoes not contain any fluorinated greenhouse gases (aslisted in Annex 1 of the EU regulations 517/2014), which
are all highly desirable in industrial cleaning applications likevapor degreasing.
Opteon™ SF80 is a blend of proprietary fluids and trans-1,2-dichloroethylene (t-DCE) with azeotrope-like properties.
Its exceptional solvency power (Kb value = 99) makes it an
ideal candidate for replacement of trichloroethylene (TCE),
n-propyl bromide (nPB), benzene, perchloroethylene,
methylene chloride, and other strong solvency fluids, wheremaximum cleaning power is a requirement. Opteon™ SF80
is also a great replacement option for solvents with low to
medium solvency power, such as HCFC-225, HCFC-141b,HFEs, PFCs, CFCs, and aqueous cleaners.
Opteon™ SF80 has the ability to clean a wide range ofcontaminants. The fluid features high solvency and low
surface tension, which can improve the efficiency of a vapor
degreaser. Opteon™ SF80 is easy to use and provides
reliability with hassle-free maintenance.
