ResinTech CG8-H-BL is a dark-colored hydrogen form 8% cross-linked gel strong acid cation resin. It is a workhorse cation resin with properties similar to other products in the CG8 family. CG8-H-BL is intended for use in all industrial applications such as demineralization where a hydrogen form cation resin is required and for mixed beds where its dark color makes visual identification of the cation/anion interface plainly evident.
