Logistics and Handling
- Supply: Available in 10 and 20-liter pails, and 500 and 1000-liter IBC containers.
- Storage: Store at a temperature between 12 and 35°C, avoiding exposure to sudden temperature changes. Its shelf life is 1 year from manufacturing under normal storage conditions. It is unstable in freeze/thaw processes.
- Handling: Once the container is opened, it must be hermetically sealed again in case the remainder is reused to avoid the evaporation of the alkalizing agents responsible for keeping the ink stable. (Consult the Material Safety Data Sheet).
