3M Fluorinert FC-84 Electronic Liquid Low Boiling Testing Fluid
Material: PFC (Perfluorocarbon)
Boiling Point: 80°C
Viscosity (25°C): 0.53 cSt
Pour Point: -95°C
Packing: 20 kg / drum
3M Fluorinert FC-84 is a clear, colorless, fully-fluorinated electronic liquid designed for electronics quality and reliability testing. With a boiling point of 80°C and a pour point of -95°C, this high-purity perfluorocarbon (PFC) fluid conforms to Military Specification 883 as a detector fluid for bubble tank and negative ion detection (NID) gross leak testing. Its low viscosity of 0.53 cSt, combined with excellent thermal and chemical stability, makes FC-84 an ideal fluid for environmental stress screening, electronics testing, and low-temperature heat transfer applications.
FC-84 offers outstanding dielectric properties — dielectric strength 38 kV, dielectric constant 1.8, and electrical resistivity 1.2×10¹⁵ ohm cm — providing reliable electrical insulation for sensitive electronic components during testing. Nonflammable with zero ozone depletion potential, FC-84 ensures safe and environmentally responsible operation in testing and quality assurance environments. Its compatibility with most metals, plastics, and elastomers makes it a versatile choice for electronics manufacturing and testing applications.
