Product Description

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

  Safety and Toxicity

Cleaning of D-230 lines and vessel equipment is very simple with hot water and steam. In the event of a shallow leak of this product, the area can be flushed with water, and the waste can be treated by calcination, in accordance with federal, state and local regulations.

D-230 is harmful and can cause skin burns and eye irritation. Wear chemical shields and impermeable gloves when using this product. In case of accidental contact with this product, flush ears and eyes with water for at least 15 minutes and seek medical attention immediately If the product comes into contact with the skin, immediately rinse the skin surface with water and soap. If clothing is soaked, remove contaminated clothing and wash.

D-230 has certain toxicity. It can be taken orally or absorbed through the skin. The LD50 is 1.66g?KG in the test on mice, and the LD50 is 0.76g/KG when used in the test. 8.0 Pass DOT4-HOUR test This product is corrosive to skin.

Under normal operation, the vapor pressure of D-230 is fairly low and does not shrink much in the working environment. However, supplied air breathing protection is required to eliminate leaks and access to confined spaces.

  Typical physical properties

  application 
 

JEFFAMINE D-230 polyoxypropylene diamine is reacted with primary amine and is practically used as the most important epoxy curing agent because of its unique molecular structure. The use of D-230 produces tough, transparent, impact resistant coatings , casting and adhesives such as furniture coatings, reinforced composites, electronic lagging, and lamination use Neat D-230 amine curing agent to avoid wet halo (whitening).

JEFFAMINE D-230 can also be used in small medical equipment, industrial flooring, shipbuilding, accessories, aviation equipment.

D-230 epoxy formulation can be modified because it is compatible with many modifiers and curing agents, including other JEFFAMINE products.

  practicality 

JEFFAMINE D-230 is available in tank trucks, 55 addition drums, 430 lbs net, 5 gallon cans.

D-230 uses isocyanate to react rapidly to primary amine. The reaction can be controlled. If used in small quantities (as viscosity modifier) or with a rapid stirrer Potential salts are easily generated, such as surfactants and flame retardants .

The reactivity of D-230 can be improved by cyanoethylation, so that the reaction can be quickly cut to the bottom. Polyurea coatings are made of cyanide organisms. When D-230 is stored at ambient temperature for a long period of time, storage needs There is a nitrogen blanket to prevent occasional high temperatures, temperatures above 140°F may cause significant discoloration, no matter what the gas blanket.
