ResinTech SIR-700-HP is a granular gel weak base anion resin with unique epoxy polyamine functionality. It utilizes a secondary mechanism for chromate removal that causes chromium to precipitate inside the resin matrix when the feed pH is slightly acidic.  SIR-700-HP is intended for all chromate removal applications. SIR-700-HP is  shipped in the acid chloride form and can be special ordered in the acid sulfate form (when ordered as SIR-700-SO4).
