GA 13

Strong Base Anion Exchange Resin Type - I

DOSHION GA 13 has a strong basic unifunctional cross linked Polystyrene structure containing type -I quaternary ammonium group. It is a premium grade gel type high capacity resin supplied in Chloride form. The resin is used in industrial and domestic water demineralisation applications. The Characteristics of GA 13 : • High capacity and shock resistance • Exceptional Physical stability for a conventional gel type resin which permits a long life without the development of excessive pressure drop. • Excellent regeneration efficiency • Ideal for demineralisation, condensate polishing and chemical process applications.
