Like other 3M™ Fluorinert™ Electronic Liquids, FC-72 is thermally and chemically stable, compatible with sensitive materials, non-flammable, practically non-toxic and leaves essentially no residue upon evaporation. This unique combination of properties makes 3M™ Fluorinert™ Electronic Liquid FC-72 an ideal fluid for electronics applications, including many electronic quality and reliability tests. Key properties: typical boiling point: 56C, pour point: -90C, dielectric strength: 38 KV (0.01 inch gap), dielectric constant (1KHz): 1.76.
