Handling Precautions

Flash point is above 200ºC (open cup method), flammable but non-explosive. In case of fire, put out with foams, dry powder, steam or water.

When handling polyols, precautions should be taken to avoid exposure to the eye or prolong 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.
 

Storage

VE-220A is slightly hygroscopic and may absorb water. Containers should be kept sealed and protected from contamination of moisture and foreign materials. Containers should be kept in ventilated warehouse under room temperature.

The shelf life is 12 months.
