GEL type DIAION SK Series

SK1B resin is our “flagship” premium grade, gel-type, strong acid cation resin. It has excellent properties for industrial applications and is recommended for industrial-scale softening and demineralization applications. It has standard cross-linkage. In situations where the raw water contains oxidizing substances, the higher cross-linkage resins such as SK110 and SK112 are recommended to provide better performance and longer operating life. SK110 is also recommended for regenerable mixed bed applications.

SK104H has a low (4%) cross-linkage. It is mainly used as a catalyst and in special applications where low crosslinked density is necessary to allow penetration of large organic molecules, or where a faster reaction rate is required.
