Technical Data Sheet
JEFFAMINE® D-230 POLYETHERAMINE
PRODUCT DESCRIPTION
JEFFAMINE D-230 polyetheramine is characterized by repeating oxypropylene units in the backbone. As shown by the representative structure, JEFFAMINE D-230 polyetheramine is a difunctional, primary amine with an average molecular weight of about 230. The primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chain.
APPLICATIONS & BENEFITS
| Applications | Epoxy curing agent Reacts with carboxylic acids to form hot melt adhesives Reacts quickly with isocyanates Salts may be formed readily for surfactant use |
| Benefits | Low viscosity, color and vapor pressure Completely miscible with a wide variety of solvents, including water Provides tough, clear, impact resistant coatings, castings, and adhesives Coatings are free of surface blush prevalent with many amine curing agents |

HANDLING AND STORAGE
JEFFAMINE® D-230 polyetheramine 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.
Cleanout of lines and equipment containing JEFFAMINE D-230 polyetheramine can be accomplished using warm water and steam. In the event of spillage of this product, the area may be flushed with water.
