ResinTech CG10-BL is a premium grade strong acid cation resin in sodium form. It is dark brown in color and made from a 10% cross-linked gel. CG10-BL has the same high resistance to physical, thermal, & chemical degradation as other resins in the CG10 family. It is intended for industrial applications where the need for durability & high capacity outweigh the higher amounts of chemical needed for regeneration compared to lower cross-linked cation resins.
