Callington S-Weld PassGel-NP is a powerful fluorine-free oxidizing passivator gel for cleaning and passivating stainless steel and aluminium alloys. This multi-purpose, gel-formatted passivator significantly reduces the amount of disassembly required for both passivation and cleaning of corroded stainless steel. It removes foreign materials, prevents corrosion, and efficiently strips anodized coatings from aluminium. S-Weld PassGel-NP can be used following pickling, grinding or mechanical polishing to ensure a passive surface is obtained prior to installation or commissioning of the final product.
