Sodium dichloroisocyanurate (SDIC) Anhydrous 60%

​Sodium Dichloroisocyanurate (SDIC) is an inorganic compound. It is a colourless, water-soluble solid, widely applied for the sterilization of swimming pools and drinking water, fighting against infectious diseases, or can act as disinfectant in treating livestock, poultry and fish. Other applications of SDIC are found in wool shrinkage, textile bleaching, and industrial circulating water cleaning.

SDIC is normally supplied in powder and granular, tablet where stabilised chlorine granular (dichlor) are used very widely to chlorinate swimming pool water.

When Sodium Dichloroisocyanurate is added to water, it is rapidly hydrolysed to release free available chlorine, establishing a complex series of equilibria involving six chlorinated and four non-chlorinated isocyanurates. As free available chlorine is consumed by reaction with organic material in the water, chloroisocyanurates will rapidly dissociate and continue to release free chlorine.
