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 crosslinkage. In situations where the raw water contains oxidizing substances, the higher crosslinkage 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 low (4%) crosslinkage. It is mainly used as a catalyst and special applications where low crosslinked density is necessary to allow penetration of large organic molecules,or where a faster reaction rate is required.
