Storage & Handling
- Storage Conditions
- JEFFAMINE® EDR-148 amine may be stored under air at ambient temperatures for extended periods. A nitrogen blanket is suggested for all storage, however, to reduce the effect of accidental exposure to high temperatures and to reduce the absorption of atmospheric moisture and carbon dioxide. It should be noted that pronounced discoloration is likely to occur at temperatures above 140°F (60°C), whatever the gaseous pad.
- Cleaning of lines and equipment containing JEFFAMINE® EDR-148 amine can be accomplished using warm water and steam. In the event of spillage of this product, the area may be flushed with water. The proper method for disposal of waste material is by incineration with strict observance of all federal, state, and local regulations.
- Handling Precaution
Mandatory and recommended industrial hygiene procedures should be followed whenever our products are being handled and processed.
