DOT: The production-validated flagship. Proven at scale. Qualified by OEMs. Available now.
DOT is TreadStone's highest-performance, commercially deployed coating technology — engineered for the most severe electrochemical operating environments and qualified by large commercial fuel cell and electrolyzer manufacturers worldwide. When system designers require the maximum combination of durability, low contact resistance, and competitive total cost, DOT is the specification they write.
DOT technology deposits a precision-controlled, uniform distribution of precious metal particles onto metal component surfaces via a proprietary, patent-protected process. The result: a highly conductive electron pathway that minimizes precious metal consumption while delivering performance that conventional thin-film coatings cannot match. Less material. Lower cost. Longer life.
TreadStone's patented deposition process provides precise, repeatable control over precious metal loading across every production batch, enabling us to optimize the performance-to-cost ratio for each specific application without variation and without compromising durability.
DOT is validated by major commercial customers and leading scientific laboratories in the United States and internationally. Available with gold, platinum, ruthenium, iridium, and bimetal complexes. Compatible with stainless steel, titanium, and other metal substrates. Geometry-flexible: TreadStone coats components of any shape or size.
Production capacity: TreadStone's North American facility is scaled to deliver over 1 Gigawatt of coated components annually. If your program is scaling, we are ready to scale with it.
