Description
Sodium Dichloroisocyanurate Product Overview
Sodium dichloroisocyanurate is a white granular powder with a chlorine odor that dissolves quickly in water. The anhydrous form contains about 60% and the dihydrate about 56% available chlorine, which it releases as hypochlorous acid.
In addition, humanitarian and outdoor users rely on SDIC effervescent tablets to purify drinking water, pool operators use granules for fast shock treatment, and hospitals, food processors and farms use it for surface and equipment disinfection. Compared with Trichloroisocyanuric Acid (TCCA), it dissolves much faster.
Notably, related disinfectants in our range include Calcium Hypochlorite and HEDP (Etidronic Acid).
