ResinTech SIR-1000 is a macroporous chelating weak base anion resin. SIR-1000 is func­tionalized with picolylamine which allows the resin to maintain its chelating strength even in significantly acidic solutions. ResinTech SIR-1000 is intended for use in process baths and rinse waters in metal finishing applications. It is especially well suited for use in highly acidic trichrome plating baths. SIR-1000 is supplied in the acid sulfate form.
