DETDA can also be used as a reactive catalyst in the curing process. When the proper amount is added to polyols, DETDA accelerates the curing speed. This bigger-than-normal "catalyst" quantity avoids the sensitivity when using a small stream catalyst, and its shelf life is much longer than metal based catalysts.
DETDA is a polyurethane elastomer chain extender is very effective; also can be used as polyurethane and epoxy resin curing agent, epoxy resin, antioxidant, industrial oil and lubricants etc.. In addition, also can be used as intermediates in organic synthesis.
