LEWATIT® K 6462

Summary

Product Identification

Lewatit® K 6462 is a strongly basic, gelular anion exchange resin with uniform size beads (monodisperse) based on a styrene-divinylbenzene copolymer.

Applications:

• Hydrometallurgical processes, e.g. uranium extraction.
• Chemicals processing: extraction and recovery of anionic heavy metal complexes.

Storage and Handling

• Recommended storage conditions: above freezing point of water, under roof, dry, and out of direct sunlight.
• If the resin freezes, allow it to thaw gradually at ambient temperature before handling or use. Do not accelerate thawing.
• Avoid contact with strong oxidants such as nitric acid, which can cause violent reactions.
• Observe the safety data sheet for additional information on transport, storage, handling, safety, and ecology.
• Disposal should comply with the European waste nomenclature.
