Catalytic Coating

DSA® electrodes are activated by depositing layers of noble catalytic oxides in succession, that enable or facilitate electrochemical reaction.

Long Life


High Performance

Coating formulations are based on metals of the platinum family like iridium, ruthenium, platinum, palladium and rhodium. The composition and deposition process determine the characteristics of the coating, favouring the desired reaction, while inhibiting undesirable side reactions. Coating thickness range from 1 to 100 microns and require compliance with strict deposition protocols.
