54A028 - Surfox-N Neutralizer 208L Drum

Complete Your Stainless Steel Finishing with Walter Surfox-N

The Walter Surfox-N 208L is a high-volume neutralizing formula designed specifically for industrial environments utilizing the SURFOX electrochemical weld cleaning system. When working with stainless steel, the cleaning process involves powerful electrolytes like Surfox-T or Surfox Renew to remove heat tint and weld discoloration. However, the job isn't finished once the weld looks clean. Residual acid from these electrolytes can remain on the surface, continuing to react with the metal long after the initial cleaning is done. This can lead to "acid bloom," salt deposits, and eventually, renewed corrosion.

Surfox-N is the essential second step in the passivation process. Unlike water, which merely dilutes the acid and spreads it around, Surfox-N chemically neutralizes the acidity, bringing the surface pH back to a neutral state. This action effectively halts the chemical reaction, preventing the formation of white salty residues (frosting) that often plague improperly finished stainless steel. By ensuring the acid is completely neutralized, you allow the stainless steel's passive chromium oxide layer to reform naturally and evenly, guaranteeing the longevity and corrosion resistance of the workpiece.

This 208-liter drum is ideal for large-scale fabrication shops and manufacturing facilities with high throughput. It ensures you have an ample supply of neutralizer to match your consumption of cleaning electrolytes. The formula is biodegradable, solvent-free, and non-flammable, aligning with Walter's commitment to safer, more environmentally responsible industrial solutions. Whether you are manufacturing food-grade equipment, pharmaceutical tanks, or architectural structures, Surfox-N ensures your stainless steel leaves the shop truly clean and fully passivated.
