Cation demineralisation resin for removing calcium, magnesium, sodium, and iron ions in deionisation systems, producing high-purity water for industrial and medical use.
Cation demineralisation resin is a high-quality ion exchange resin designed to remove positively charged ions such as calcium, magnesium, sodium, and iron from water. Used together with anion resins in deionisation systems, it enables the production of high-purity water suitable for industrial, pharmaceutical, and medical applications.
Features & Benefits
Removes positively charged ions (calcium, magnesium, sodium, iron)
Works with anion resin for complete demineralisation
Produces ultra-pure water for industrial, laboratory, and medical use
Strong acid and weak acid grades available
Stable and durable performance across regeneration cycles
Storage Guidelines
Keep resins moist at all times. Store between 15 °C and 45 °C in sealed packaging or under a water layer. Avoid direct sunlight and drying conditions.
Safety Notes
Regeneration requires the use of strong acids (HCl or H₂SO₄). Always handle with appropriate PPE to prevent skin or eye contact.
