LEWATIT® K 6362

Summary

Product identification

Lewatit® K 6362 is a strongly basic (type I), gel-type ion exchange resin. It is based on a styrene-divinylbenzene copolymer with a very narrow bead size distribution (monodisperse grade).

Common Description:

• Delivery form: Cl⁻
• Functional group: Quaternary ammonium salt, type 1
• Matrix: Styrenic
• Structure: Gel
• Appearance: Light yellow, translucent

Applications

In its delivered chloride (Cl⁻) form, Lewatit® K 6362 can be used for:

• Recovery of precious metal cyano and chloro complexes from waste water or process streams.
• Removal of anionic heavy metal complexes from hydrochloric acid.
• Recovery of uranium from both carbonate and sulfuric acid leach solutions.

In its hydroxide (OH⁻) form, Lewatit® K 6362 is particularly suitable for:

• The removal of mercaptane sulfur from hydrocarbon streams.
• Catalysis of organic reactions of small polar molecules in the temperature range from 30 to 60 °C.

Operating limits

Electrical

N/A

Mechanical / hydraulic

• Uniformity coefficient (max.): 1.1
• Mean bead size (d₅₀): 0.62 (±0.05) mm
• Bulk density for shipment (±5%): 690 g/L

Additional Information

• Storage: Recommended to store at temperatures above freezing, under roof, in dry conditions, away from direct sunlight. Frozen resin should thaw gradually at ambient temperature.
• Packaging stability: Limited to 24 months under recommended storage conditions.
• Safety: Avoid contact with strong oxidants (e.g., nitric acid). Refer to the safety data sheet.
• Disposal: According to European waste nomenclature.
