General Product Description of Cation Resin
The “G-Ion” brand GC-100 is a sort of Cation resin that has a sulfonic group (-SO3H) in the styrene-diethylene benzene copolymer with a 7% cross-linked degree. It is used mainly to soft hard water and produce pure water, as well as used in the hydro-metallurgy and sugar producing and medicine and no sodium glutamate industry, it can be used as a catalyzer and dehydrating agent.
Executing standard: GB13659-1992 DL/T 519-2004 SH2605.01-2003
