JEFFAMINE® EDR-148

• Can be formulated to cure at room temperature
• Rapid cure at elevated temperatures
• Excellent thermal shock resistance in cured epoxies
• Low viscosity – Used as a reactive diluent in epoxy formulations
• High purity – Suitable as a molecule for synthesis of high-purity chemicals / intermediates
• High reactivity – Provides fast cure in epoxy adhesives
• Flexible and hydrophilic – Used as a monomer in polyamide applications instead of ethylene amines
• Thermal shock resistant – Suitable for epoxy electronic encapsulation, increasing life cycle of devices
• EHS profile – Not listed as a substance of very high concern

Mandatory and recommended industrial hygiene procedures should be followed whenever our products are being handled and processed. 

• 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.
