54A041 - Walter Surfox-E Stainless Steel Electrochemical Marking Solution, 100ml

Technical Overview of Surfox-E Etching Electrolyte

The Walter Surfox Etching Solution (54A041), known as Surfox-E, is a specialized chemical formulation designed for the electrochemical marking of stainless steel substrates. Engineered to function specifically with the DC (Direct Current) output mode of Walter Surfox weld cleaning systems—including the MINI SURFOX, SURFOX 204, and SURFOX 203—this solution facilitates a controlled oxidation reaction on the metal surface. Unlike abrasive mechanical engraving or surface-level ink printing, the electrochemical process utilizes this electrolyte to alter the surface properties of the stainless steel, resulting in a permanent white etch that is integral to the material.

This 100ml unit is formulated to provide consistent conductivity and reaction speed, ensuring crisp, high-definition edges when used in conjunction with appropriate stencils. The solution is compatible with standard graphite marking tips and marking pads found in Surfox marking kits. It is particularly effective for industrial applications requiring durable traceability, such as the application of serial numbers, QR codes, barcodes, and data matrices that must withstand cleaning, passivation, and environmental exposure. The solution works by selectively etching the exposed areas of a stencil while the surrounding metal remains unaffected, providing a high-contrast finish that enhances legibility on various grades of stainless steel.

Operators must ensure the machine is set to DC mode to achieve the etching effect; AC mode is typically reserved for cleaning and polishing. The Surfox-E solution is non-flammable and designed to be safer than traditional acid etching pastes, although standard PPE for handling industrial chemicals is recommended. This product represents a critical consumable for the Surfox marking ecosystem, enabling precise and permanent identification capabilities directly on the shop floor.
