LEWATIT® CNP LF Na Ag

Summary

Product identification

Lewatit® CNP LF Na is a food-grade, weakly acidic, macroporous cation exchange resin based on crosslinked polyacrylate. It is bead-shaped with a special bead size distribution.

Application

Lewatit® CNP LF Na is suitable for the decarbonisation and softening of drinking water in household filter systems, especially cartridges.

Storage and Handling

• Storability: max. 6 months
• Storability temperature range: -20 to 40 °C
• It is recommended to store ion exchange resins at temperatures above the freezing point of water, under roof, in dry conditions, and without exposure to direct sunlight.
• If resin becomes frozen, it should be left to thaw gradually at ambient temperature and not handled mechanically.
• Do not attempt to accelerate the thawing process.
• Strong oxidants (e.g., nitric acid) can cause violent reactions.
• Observe the safety data sheet for additional information.
