72060002 - Vanguard Stainless Steel Neutralizing Paste 2kg

Professional Grade Acid Neutralization for Stainless Steel

The Vanguard Neutral Paste Inox is a specialized chemical formulation designed to serve as the critical second step in the chemical treatment of stainless steel welds. Following the application of pickling pastes—which utilize strong acids like hydrofluoric and nitric acid to remove weld oxides, heat tint, and chromium-depleted layers—it is imperative to thoroughly neutralize the surface. Failure to do so can leave microscopic acidic residues within the surface profile, leading to latent corrosion, pitting, and a failure of the passive layer to reform correctly. This 2kg jar provides a generous supply of neutralizing agent suitable for industrial fabrication environments.

Chemically, this paste is engineered to react with the low-pH residues left by pickling agents, raising the pH on the metal surface to a neutral level. This reaction not only stops the etching process immediately but also facilitates the formation of the chromium oxide passive layer, which is the mechanism by which stainless steel resists rust. The paste format is particularly advantageous over liquid neutralizers for field applications or large structures, as it possesses a viscosity that allows it to cling to vertical seams, overhead welds, and complex geometries without rapid runoff. This ensures adequate contact time for the neutralization reaction to occur thoroughly across the entire treated area.

From an environmental and safety perspective, using Vanguard Neutral Paste Inox is a best practice. Rinsing active pickling paste directly with water can result in runoff with a dangerously low pH, potentially violating local wastewater disposal regulations. By applying this neutral paste first, the bulk of the acidity is neutralized on the workpiece, resulting in a rinse water that is significantly closer to neutral pH and safer to handle. This product is an essential component of any compliant stainless steel surface treatment protocol, ensuring that the structural and aesthetic integrity of the stainless steel is maintained long after the fabrication process is complete.
