Pickling & passivation for stainless steel

2-in-1 Pickling & Passivation for Stainless Steel. 

SWHTR® is the best choice to ensure safe and effective pickling and proper passivation every time to inhibit future corrosion and in-service failure of the weld zone area.  It also eliminates the need for mechanical methods which release dangerous hexavalent chrome and chrome-6 particles into the air. 

SWHTR® is safe and effective on all grades of stainless steel.

APPLICATION:

Allow hot, newly welded surface to cool completely before use.  Clean and degrease surfaces before application, especially when using oil-based anti-spatter products.

ALWAYS MIX PRODUCT WELL OR SHAKE CAULKING TUBES WELL BEFORE USE. 

When applying by synthetic brush, apply a liberal amount of SWHTR® EnviroPaste directly on the treatment area. Ensure complete coverage of .078” – .120” (2mm-3mm) thickness with at least a 1-2 inch (25mm – 50mm) band of product that covers the underlying weld seam and any adjacent discoloration. Once applied, DO NOT agitate or interfere with the working product.   

When applying by pressure pot sprayer (REFER TO RECOMMENDED SPECS), ensure complete coverage that liberally covers weld seams and any discoloration. Protect areas not to be treated from overspray. Once applied, DO NOT agitate or interfere.

SWHTR® Liquid is designed for dip / immersion tanks ONLY.  It is not designed for spray application as it will not cling to the surface. 

Refer to individual TDS sheets for more detailed instructions
