TopFlex surface coating

Optics Balzers now also offers a surface coating that repels dirt, liquids, and chemicals. TopFlex is a surface coating with hydrophobic characteristics. It is chemically resistant to water, oils, and fats. Moreover, TopFlex is dirt-repellent and easy to clean. It offers excellent adhesive properties on the substrate and is suitable for a wide variety of cleaning processes.

TopFlex is a highly planar and enclosed surface coating and can be combined with all coating systems, as it is spectrally neutral in the visible and IR regions. Its hydrophobic properties are especially evident at a wetting angle up to 120°. At this wetting angle, fluids and dirt cannot adhere to the surface, or only very poorly. This makes such surfaces very easy to clean. Thanks to their film stability up to 300°C, TopFlex-coated components can be applied even in adverse conditions. The coating is also resistant to scratching and corrosion.

The coating is suitable for applications in which ease of maintenance and resistance to dirt are required. The coatings are used in endoscopy, in sensor systems, and in special-purpose cameras. Other fields of application include research activities, metallic coatings, or medical devices.
