DETDA is a type of aromatic diamine, ethyl and methyl groups, which makes the activity of is much lower than that of TDA. The reaction rate with polyurethane prepolymer several times faster than DMTDA, about 30 times faster than MOCA. Mainly used in RIM polyurethane system and spray polyurethane (polyurea) elastomer coating system, with a fast reaction rate, short release time, high initial strength, product resistance to hydrolysis, heat and so on. In addition to the product can also be used as elastomer, lubricants and industrial oil antioxidant, and chemical intermediates.
1. Packaging and transport：
Packaging for 1000KG/IBC barrels, 200kg drums or ISOTANK, the special packaging in accordance with the requirements of customers.
Stacked in a cool/ dry/ ventilated place, keep away from heat/ fire, to prevent the direct sunlight, to avoid high temperature, do not sharp object collision damage.
