Frequently Asked Questions
What is the available chlorine content of SDIC 55% granules?
SDIC 55% granules contain 55% available chlorine (AC), making them a highly effective disinfectant suitable for a wide range of applications including water treatment, agricultural disinfection, and industrial use.
What is the difference between SDIC 55% and SDIC 60%?
SDIC 55% is the dihydrate form of sodium dichloroisocyanurate, containing 10–14% water content, which gives it a slightly lower available chlorine content (55%) compared to SDIC 60% (anhydrous form). SDIC 55% offers milder chlorine odor, lower irritation, and is classified as a Class 9 dangerous good, while SDIC 60% is classified as Class 5.1 oxidizer. SDIC 55% is often preferred for applications where safety and handling ease are priorities.
Is SDIC 55% safe for swimming pool use?
Yes. SDIC 55% is widely used for swimming pool disinfection. It effectively kills bacteria, viruses, and algae while maintaining water clarity. When used at the correct dosage and with proper pH management (5.5–7.0), it is safe for swimmers and aquatic organisms.
What packaging options are available for SDIC 55% granules?
SDIC 55% granules are available in HDPE drums, fiber drums, and plastic buckets in standard sizes of 1kg, 5kg, 10kg, and up to 50kg. For bulk orders, jumbo bag packaging and custom solutions are also available. All packages are clearly labeled with product information, safety notes, and usage instructions.
Can SDIC 55% be used in agriculture and aquaculture?
Yes. In agriculture, SDIC 55% is used to prevent and control fungal, bacterial, and viral crop diseases via seed soaking, spraying, and root irrigation. In aquaculture, it is applied for pond cleaning, water body disinfection, fish seed disinfection, and equipment disinfection in fish, shrimp, crab, and frog farming to prevent bacterial and viral diseases.
What granule mesh sizes are available for SDIC 55%?
SDIC 55% granules are available in two mesh size ranges: 8–30 mesh and 20–60 mesh. Different granule sizes are suited to different application scenarios — coarser granules are typically used for slow-dissolving applications such as swimming pools, while finer granules dissolve more quickly for rapid disinfection needs.
