Fluorine‑free oxidizing passivation gel specially formulated for aluminum and aluminum alloys. Designed for in‑field cleaning and passivation with a thick gel consistency for easy application.
Specifically for aluminum and aluminum alloys — ideal for fabrication and surface prep
Gel formulation for controlled application on vertical, horizontal, and complex surfaces
Fluorine‑free for use where fluorine compounds are prohibited
Removes free iron and contaminants after pickling, grinding, or polishing
Improves product quality by enhancing surface passivity before assembly
Conforms to industry standards including ASTM A380/A967 and Collins Aerospace RPS 15.00 & 15.52
Callington S‑Weld PassGel‑NP is a heavy‑duty passivator and cleaner in a user‑friendly gel form, engineered for aluminum and aluminum alloy surfaces. Its thick consistency allows for accurate and efficient application to both large and detailed components. This gel both cleans and promotes the formation of a passive oxide layer, reducing corrosion risk and preparing metal surfaces for long‑term service.
Designed for in‑field use, PassGel‑NP minimizes the need for disassembly of equipment or structures prior to treatment. After application, rinse with potable water and dry thoroughly to prevent staining.
