Noble Metal Oxide Coating
Whether operating in soil, fresh water, seawater or mud, mixed metal oxide coatings demonstrate high chemical stability, even in environments with a low pH value. Based upon accelerated life testing, conducted by an independent laboratory, our MMO coating has been proven to have an increased life expectancy when compared with other similar products on the market. Differing coating thickness and different noble metal oxide ratios are available on request.
◉ Ir–Ta Mixed Metal Oxide Catalyst
The iridium-tantalum mixed metal oxide catalyst is recommended for use in soil or fresh water, where there is either no
chloride ions or low chloride ions present.

PRACTICAL APPLICATION
For new build structures, the mesh ribbon anode is simply attached onto the rebar embedded inconcrete/mortar before the concrete is poured. For retrofit applications, the mesh ribbon anode can be inserted into slots cut into the concrete surface.
