Product Short Description: Prevent SMUT formation, discoloration and toxic fumes due to nitric acid pickling by using Safe Passivator Liquid which is acid free.

Product Description:

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.

Product 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.

How to make safety as a priority while using Passivation Liquids - Use RXSOL Safe Passivator Liquid 630!

Step	Procedure
1. Surface Preparation	Ensure the stainless-steel surface is free from heavy grease, oil and loose contamination. Where required, pre-clean with a suitable alkaline or neutral degreaser.
2. After Pickling	Thoroughly rinse away the pickling chemical with clean water before applying Safe Passivator Liquid 630.
3. Application	Apply uniformly by low-pressure spray, brush, immersion or circulation depending upon the equipment and surface geometry.
4. Contact Time	Allow approximately 10-15 minutes contact time under normal conditions. Do not allow the product to dry completely on the surface.
5. Final Rinsing	Rinse thoroughly with clean fresh water. High-pressure rinsing may be used where appropriate.
6. Drying	Allow the treated stainless-steel surface to drain and dry naturally or use clean, oil-free compressed air where required.

Treatment of Flash Rust / Smut

Where smut or light flash rust appears immediately after pickling, apply Safe Passivator Liquid 630 while the stainless-steel surface is still wet.

Allow approximately 10-15 minutes reaction time and then rinse thoroughly with clean water.

For heavier contamination, pre-clean the affected surface, rinse with water and then apply Safe Passivator Liquid 630 to the clean, wet surface.

Reduction of Nitric Fumes During Pickling

Where nitric-acid-containing pickling products are being used, Safe Passivator Liquid 630 may be applied as a fine mist over the wet treated surface as part of the post-pickling procedure to help suppress residual fuming.

This application should not be considered a substitute for proper ventilation, extraction or required PPE.

Simple spray, brush or circulation application
Suitable for general industrial and marine stainless-steel maintenance

Remarks:

Materials of Application

The product can be applied using suitable chemical-resistant equipment, including:

Chemical-resistant low-pressure spray equipment
Acid/chemical-resistant pumps
Plastic or compatible stainless-steel application equipment
Brushes and suitable manual application systems
Immersion tanks
Circulation cleaning systems

Important Operating Notes

The surface should be thoroughly rinsed after pickling before passivator application. For best results, apply the passivator uniformly so that the complete stainless-steel surface remains wetted throughout the required contact period.

Do not permit loosened pickling residues, chloride-rich rinse water or contaminated rinse water to remain on the stainless-steel surface after treatment.

Where high-purity service, pharmaceutical equipment, food-contact equipment or critical process systems are involved, the final rinse-water quality and acceptance criteria should be established according to the applicable plant procedure.

Suitable Stainless-Steel Applications

Safe Passivator Liquid 630 can be considered for general passivation treatment of stainless-steel:

Tanks • Pipelines • Heat exchangers • Process vessels • Fabricated components • Stainless-steel structures • Marine equipment • Pumps • Valves • Tubing • Welded assemblies

Compatibility and treatment effectiveness should be verified on the actual stainless-steel grade and surface condition before large-scale application.
