Production Types

Packaging, Handling & Storage
Store in new steel drums, 200KGS/drum.
Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Store in cool place.
The shelf life is 12 months. After that, pre-testing should be conducted before use.
Safety Precautions
When handling polyols, precautions should be taken to avoid exposure to the eye or prolonged contact with the skin. If eye contact occurs, flush with plenty of water. If skin contact occurs, wash exposed areas thoroughly with soap and water.
