Applications

Used extensively as a catalyst to promote both gelling and blowing reactions in the production of flexible, semi-rigid and rigid polyurethane foams, as well as, elastomers and adhesives It is also used in polyurethane coating applications. The crystalline catalyst accelerates the reaction between water and Isocyanate and the Isocyanate and organic hydroxyl groups. It can also be used with a blowing co-catalyst. In rigid system it is frequently used with dimethylethanolamine (DMEA) catalyst. TEDA is also available in solutions of dipropylene glycol, and ethylene glycol Also used as catalyst for reaction of aromatic diamine with aromatic acid anhydride to manufacture polyimide, eg, Kapton film, which is used for aerospace and electrical industries. TEDA is also used as a raw material for manufacture of agrochemicals like herbicide and also in organic synthesis as acid absorber.
