Tri-iso distributes a wide range of aliphatic 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.  Primary aliphatic diamines react very quickly, especially compared to sterically-hindered secondary amines.
