Durability and protection with Ematal
RODI devices are specially designed for investigating the drift of organisms in bodies of water. The Ematal coating gives the housings strong corrosion protection and thus increases the longevity of the devices in continuous underwater use.
Special requirements for ecological applications
The devices, which are used directly in natural watercourses, must be particularly resistant in order to withstand environmental influences. The Ematal coating protects the cast aluminum housing from abrasion and wear, which is particularly important in rivers with gravel and stone sediment flowing through them.
Prototype of the RODI device – in series production, all parts are Ematal-coated for better integration into the environment.
Non-invasive design for natural observations
Thanks to the matt Ematal coating, the devices look like part of the natural river landscape and barely stand out from the background. While bare aluminum would have a disturbing light reflection effect on the water world, RODI remains inconspicuous thanks to Ematal and thus supports non-invasive research on biodiversity in rivers. RODI was developed by The Stocker Lab research group at ETH Zurich.
PFAS-free – A sustainable alternative
The sliding properties of hard anodized surfaces are often improved by impregnating them with PTFE (polytetrafluoroethylene). However, PTFE belongs to the group of per- and polyfluorinated alkyl compounds (PFAS), the use of which is being increasingly regulated due to their environmental and health risks. The Ematal coating, on the other hand, naturally offers excellent anti-friction and anti-wear properties, without any PTFE impregnation. This makes it an environmentally friendly solution that meets current and future requirements for sustainable products.
