Power Fluide GmbH is one of the leading producers of magnetic nano fluids. An early application for their specialized nano fluids is as printable MICR inks which are printed as a security feature on bank checks. In the following years, due to various customer inquiries, new special liquids and new fields of application were added. Today Power Fluide GmbH is offering magnetic nano-fluids that can be either water or oil based. The liquids are printable for various industrial applications and have the added advantage that they do not require UV drying. Customers of Power Fluide GmbH obtain their personalised fluid, unique in the world, which enables them a printable, invisible certificate of authenticity on their products. The company additionally has customers who use Power Fluide products as a base component liquid in their own applications. Furthermore, special nano-fluids can be used as lubricants and flexible regulators, for example, in enhancing the performance of electric motors or shock absorbers.
