Storage & Handling
Storage and Handling
- DIAMMIN S-25 should preferably be stored in stainless steel tanks.
- It is suggested to keep the product at temperature below 40°C, it is preferable to avoid heating above 60°C and to store under nitrogen in order to minimise darkening phenomena.
- DIAMMIN S-25 is a cloudy liquid at room temperature and it becomes homogeneous and transparent at about 40°C.
- DIAMMIN S-25 becomes a solid wax at te mperature lower than 20°C. Avoid also contact with strong oxidizers and strong acids.
