About SDIC Granular

Sodium dichloroisocyanurate — also written NaDCC or dichlor — is a stabilised chlorine donor supplied as a white granule. It is one of the standard sanitiser chemistries used in swimming pools, potable water treatment and general water disinfection. We supply it in 56% and 60% available-chlorine grades and in two particle sizes, packed for both site use and bulk handling.

Frequently asked

Questions we get about SDIC Granular

What does RNJ Trading supply?
Swimming pool and water treatment chemicals. The range covers chlorine sanitisers — SDIC granules and tablets, TCCA 90, calcium hypochlorite and sodium hypochlorite — alongside pH and alkalinity correctors, a coagulant for water clarity, and cyanuric acid stabiliser. Everything is available in pail, drum and bulk-bag formats. The full list, with grades and pack sizes, is on the products page.
What is SDIC?
SDIC — sodium dichloroisocyanurate, also written NaDCC or dichlor, CAS 2893-78-9 — is a stabilised chlorine donor supplied as a white granule or a pressed tablet. It is one of the standard chlorine chemistries used in swimming pools and in water disinfection. We supply it in 56% and 60% available-chlorine grades, in two particle sizes, and in tablets from 1 g to 200 g.
What is the difference between SDIC, TCCA and calcium hypochlorite?
They are three different chlorine chemistries. SDIC and TCCA are chlorinated isocyanurates and are stabilised, meaning they contain cyanurate; calcium hypochlorite is unstabilised and contains calcium instead. They differ in available chlorine, in how quickly they dissolve and in whether their solution is acidic or alkaline — the typical values for each are published on its product page. Which one suits a given installation is a decision for the person responsible for that water system.
What grades and pack sizes are available?
SDIC granules and tablets are supplied in 5 kg and 10 kg pails, 25 kg and 50 kg HDPE drums and 1,000 kg jumbo bags. TCCA 90 comes in pails and 25 kg and 50 kg drums. Calcium hypochlorite comes in 45 kg and 50 kg drums and in pails. The pH range — sodium bisulphate, sodium bicarbonate and soda ash — comes in 25 kg and 50 kg bags and jumbo bags. Sodium hypochlorite is supplied in cans, drums, IBCs and bulk.
