54A063 - Walter Surfox-G pH Neutral Electrolyte Spray 500ml

Technical Overview of Walter Surfox-G Electrolyte

The Walter Surfox-G (54-A 063) is a specialized electrolyte solution engineered for the electrochemical cleaning and passivation of stainless steel welds. Unlike conventional pickling pastes or highly acidic electrolytes (such as those containing hydrofluoric or nitric acid), Surfox-G utilizes a pH-neutral formulation. This chemical composition significantly mitigates safety risks for operators and reduces the environmental burden associated with hazardous waste disposal. The solution is designed to possess high ionic conductivity, which, when used in conjunction with a Surfox weld cleaning machine, facilitates the rapid removal of heat tint, oxidation, and discoloration from the heat-affected zone (HAZ) of TIG welds.

The 500ml spray bottle delivery system allows for precise, localized application of the electrolyte directly onto the workpiece. This ensures that the weld seam is adequately wetted prior to the application of the cleaning wand, optimizing the electrochemical reaction. Because the solution is pH neutral, it does not etch or dull the surface of the stainless steel base metal, preserving the original finish—whether mirror-polished or brushed. Furthermore, the neutral nature of the fluid eliminates the strict requirement for a secondary neutralization process typically demanded by acidic cleaners to prevent acid pitting. However, a thorough water rinse is recommended to remove any residual salts and contaminants post-cleaning.

Surfox-G is particularly indicated for applications in sectors with stringent health and safety regulations, such as food and beverage processing, pharmaceutical manufacturing, and architectural fabrication. It effectively restores the chromium oxide passive layer on the stainless steel surface, ensuring corrosion resistance is maintained. The product is compatible with the full range of Walter Surfox electrochemical cleaning units and pads. By utilizing this electrolyte, facilities can achieve ASTM A967 and ASTM A380 standards for passivation without the handling and storage liabilities associated with dangerous mineral acids.
