This fully-fluorinated liquid is ideal for use in many single-phase heat transfer applications - especially in the semiconductor manufacturing industry - and is widely used in testing applications.


Listed below are key applications for FC-40. Documents specific to the application are listed to the right.

Heat Transfer Fluids
For heat transfer applications that require a higher boiling point than 3M™ Fluorinert™ Electronic Liquid FC-3283, Fluorinert liquid FC-40 (155°C boiling point) is an ideal choice. It is well-suited to a variety of heat transfer applications - especially in the electronics industry.



Testing Fluids

The high dielectric strength and wide liquid range of Fluorinert liquid FC-40 allows its use in a variety of testing applications, including electronic reliability, hermetic seal/gross leak, and thermal shock testing.

Hermetic seal/gross leak testing generally follows Military Standards 883-1014, 750-1071 and 202-112; FC-40 liquid conforms to these standards. Thermal shock testing generally uses Military Standard 883-1011 specifications; FC-40 liquid also conforms to these specifications.
