TRiiSO distributes a wide range of aromatic polyamines that allow formulators to produce high quality polyureas.  Polyamines contain reactive amine (NH) groups which react with isocyanate (NCO) groups on isocyanates to form polyureas.  Sterically hindered aromatic diamines will react much slower than standard secondary amines, and significantly slower than primary amines.   The slower reactivity will allow formulators to produce parts/coatings with enhanced aesthetic quality.
