Ferrotec EMG Series - Water-based Ferrofluid
Type: EMG 304

Product Description

Ferrotec’s EMG 304 Ferrofluid is a member of Ferrotec’s family of EMG Series - Water-based ferrofluids. Unlike Ferrotec's APG series of ferrofluids that have been optimized for audio speaker applications, Ferrotec’s EMG Series ferrofluids address a broad range of application requirements and can be used for experimentation and application development. Ferrotec's water-based EMG Series are typically used in applications where rapid evaporation or the ability to mix ferrofluid into a water-based system is required. EMG 304 ferrofluid is Black-brown fluid and uses Anionic surfactant.
