Sterically Hindered Aliphatic Diamines

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.  Sterically-hindered aliphatic diamines react slower than standard secondary diamines, and significantly slower than primary amines.  This slower reactivity allows for better aesthetics of the finished polyurea part or coating.
