Callington S-Weld Passivatorgelis a powerful oxidising gel for the passivation of stainless steel, duplex steel and Inconel alloys. S-Weld Passivator can be used following pickling, grinding or mechanical polishing of stainless steel to ensure a passive surface is obtained prior to installation or commissioning of the final product.
Directions For Use
1. The surface should be pre-cleaned to remove oils and greases before applying the passivating agent. Use Callington S-Weld Brite Wash. Any contamination will shorten the life of the passivating gel.
2. Stir the gel to ensure a smooth consistency and apply S-Weld Passivator using the acid-resistant brush provided.
3. Application Times - Refer to TDS for application times
4. Rinse thoroughly with clean potable water, dry surfaces to prevent water staining (smut). If a neutralizing agent has been used this must be followed by rinsing again with clean potable water and surfaces should be dried to prevent water staining.
