The DOT coating products offer the best value in coating performance under the most severe system operating environments. The DOT coating is being used in specialty commercial fuel cells and electrolyzer systems where durability, low contact resistance, and best value pricing are key attributes required by the system designer.
The DOTS technology uses a small number of precious metal particles that are deposited on the metal component surfaces using a proprietary processing method. The small precious metal particles provide a conductive pathway for electrons to enter and exit the system. Being highly conductive, the small dots reduce the amount of precious metal used thereby assuring our customers the best value of low contact resistance, long durability, and low costs.
