Strong acid cation exchanger

  • Structure of matrix – gel, copolymer of styrene and divinylbenzene.
  • Active group – sulfonic acid group.
  • Known for its high chemical resistance to alkali, acid and oxidant.
  • Resistant to high temperatures (110-120°C).
  • Mechanically durable.
  • Exchange capacity is only slightly dependent on pH.


Area of employment

  • water softening and salt removal (in water treatment);
  • separation and recovery of non-ferrous and rare metals in hydrometallurgy;
  • cleaning of redistributed water and wastewater;
  • regeneration of waste generated in the process of galvanic coating and metal treatment;
  • separation and purification of various materials in chemical industry;
  • as catalyst in organic synthesis.

For regeneration (conversion of the exhausted resin into H-form), KY-2-8 is treated with hydrochloric or sulphuric acid solution. Regeneration after use in water softening is performed with the help of 8-10% solution of sodium chloride.

Package – polyethylene bags (weight of wet product – 20kg).

Transportation – covered motor vehicles or railway transport.

Storage in warehoses at the temperature not low than +2°C.

Before use, frozen anion exchanger should be kept in a warehouse at +10-20°C in the producer's package until de-freezing for 2-4 days.

Expiry date – 12 months from the day of production.
