54A036 - Walter Surfox-M Electrochemical Marking Fluid 5L

Technical Electrochemical Marking Electrolyte

Walter Surfox-M 54A036 is a high-performance electrolyte solution engineered specifically for the electrochemical marking of stainless steel surfaces. This fluid is chemically formulated to facilitate a controlled oxidation reaction when used in conjunction with an alternating current (AC) power source, typically provided by a Surfox weld cleaning unit. The process creates a stable, permanent black oxide mark on the surface of the metal without removing material or altering the dimensional tolerances of the part. This makes it superior to mechanical engraving or laser marking for applications where surface integrity is paramount.

The marking produced by Surfox-M is not a coating; it is a molecular conversion of the stainless steel surface. Consequently, the mark exhibits exceptional resistance to mechanical abrasion, chemical cleaning agents, and environmental factors such as UV radiation and salt spray. This durability makes it an ideal solution for creating permanent identification tags, schematics, and traceability codes on equipment destined for harsh environments, including food and beverage processing, pharmaceutical manufacturing, and marine applications. The solution is compatible with both disposable vinyl stencils and durable permanent stencils, offering flexibility for both custom one-off jobs and repetitive production runs.

Operational Usage:

• Mode Selection: Must be used in AC mode on the Surfox machine to achieve the black oxidation effect. DC mode is reserved for cleaning and polishing.
• Application: The solution is applied using a marking wand or pad saturated with the fluid, pressed over a stencil against the workpiece.
• Neutralization: While the marking process is less aggressive than cleaning, it is recommended to neutralize the surface after marking to remove any residual electrolyte and ensure long-term passivation.

Supplied in a 5-liter container, this bulk format reduces downtime associated with frequent reordering and is cost-effective for industrial operations. The formula is developed to be highly conductive yet safe for the operator when used according to safety data sheet (SDS) guidelines, providing a reliable and efficient method for permanent metal identification.
