Project Description
DETDA is equal to Ethacure 100 and Lonza DETDA 80. DEDTA is the short name of diethyl toluene diamine.
It is a very effective chain extender of polyurethane elastomer, in particular for RIM (reaction injection molding) and SPUA (Spray Polyurea Elastomer).
Moreover, DETDA (similar to Ethacure) can also be used as a curing agent of polyurethane and epoxy resin antioxidant of epoxy resin, industrial oil, and lubricants.
In addition, diethyl toluene diamine can also serve as an intermediate in organic synthesis.

Packing and Storage:
In 200 kg iron drum/as customer’s special requirements.
Handle with care. DETDA should be stored in a cool, dry and draughty place. Shelf life is one year. Then, DETDA (like Ethacure 100) can still be used if qualified after re-check.
