Safe Passivator Liquid 630

SKU: RXSOL-38-1630-025
RXSOL Safe Passivator Liquid 630 is an acid-free liquid passivating and surface-conditioning treatment developed for stainless steel surfaces after pickling, fabrication, welding, grinding, blasting and other mechanical or chemical treatments.
 
During fabrication and pickling, the natural passive chromium-rich oxide layer of stainless steel may be disturbed. Residual free iron, smut and surface contamination can also contribute to flash rusting, staining and discoloration.
 
Safe Passivator Liquid 630 is designed to assist in the restoration and stabilization of the passive surface condition while helping remove residual free iron and reducing the possibility of subsequent staining.
 
The product is particularly suitable where a safer, nitric-acid-free passivation treatment is preferred.

Application

Where to use Safe Passivator Liquid 630?

Safe Passivator Liquid 630 is recommended for:

Passivation after pickling: Applied to freshly pickled stainless-steel surfaces to promote restoration of the protective passive layer.

Passivation after mechanical treatment: Suitable after grinding, brushing, polishing, blasting and fabrication operations that may disturb the stainless-steel passive surface.

Free iron / smut removal: Helps remove traces of free iron and surface residues that may otherwise cause rust spots or discoloration.

Flash rust prevention: Particularly useful immediately after pickling where flash rust or brown staining may occur during drying.

Post-pickling treatment: Can be used as a final conditioning treatment before equipment is returned to service.
