Modified Aliphatic Amines are room temperature reacting curing agents derived from aliphatic amines. The basic aliphatic amines are modified to reduce their vapor-pressure and thereby reduce their corrosiveness. The modification is also done to optimize the hardness, reactivity, handling time of system and also to improve the carbonation resistance.
