Products Description
JEFFAMINE D-230 polyoxypropylene diamine is one of Huntsman's polyamine series products, the main chain repeats propylene oxide units. As shown in the structure above, D-230 is a difunctional primary amine with an average molecular weight of about 230, and its functional group is located on the second carbon atom at the end of the aliphatic polyether chain.

Apply
JEFFAMINE D-230 polyoxypropylene diamine undergoes primary amine reaction, because of its unique molecular structure, it is used as the most important epoxy curing agent. The use of D-230 can be Produces tough, clear, impact-resistant coatings, castings and adhesives such as furniture coatings, reinforced composites, electronics lagging, and lamination Use of Net D-230 Amine Curing Agent to avoid blush (whitening) .
JEFFAMINE D-230 can also be used in small medical equipment, industrial floors, shipbuilding, Accessories, aviation equipment.
D-230 epoxy formula can be improved, because it can be compatible with many modifiers, Compatible with curing agents, including other JEFFAMINE products.
Practical Sex
JEFFAMINE D-230 can be used in tank trucks, with a net weight of 430 lbs in a 55-gallon cylinder, and in a 5-gallon can.
D-230 uses isocyanate to react quickly with primary amine. The reaction Can be controlled. Use in small quantities (as a viscosity modifier) or with a quick stirrer Potential uses Salt tends to produce, such as surfactants and flame retardants.
The reactivity of D-230 can be improved by cyanoethylation to make the reaction rapid Bottom cut. Polyurea coatings are made of cyanide organisms. When D-230 is stored at ambient temperature for a long period of time, the storage tank needs to have a nitrogen layer to prevent occasional high temperatures. Significant damage may occur if the temperature exceeds 140°F. Fading, no matter what gas cushion.
