SDDC solution should be stored in its original container or a stainless steel tank in a ventilated location protected from frost.

Keep away from acids to avoid release of CS2.

The 40% solution crystalizes at –2°C. The 42% solution crystallizes at +3°C.

SDDC solution corrodes copper, zinc and their alloys. On contact with ordinary steel it rapidly forms a black precipitate.

The following plastics are suitable for joints and pipes: HD polyethylene, polypropylene, polytetrafluoro-ethylene (Teflon) and polyamide (Nylon 6).

Our trails have shown that SDDC solutions show no variation in assay after storage in the original pack below 30°C for 24 months.

SDDC is very toxic to aquatic organisms, release into the environment must be avoided. In the event of accidental spillage, cover the product with an absorbent material and send to a treatment plant for chemical waste. Do not release SDDC solutions into the drains.
