Cycloaliphatic structures have unique characteristics which allow amine curing agents to be less toxic and provide better mechanical strength when compared to other based curing agents. Moreover, these curing agents are able to form a more stable and cross-linked polymer network which in turn enhances their weather resistance. This leads to improved abrasiveness and resilience in addition to increased hardness and color stability. Due to the capability to withstand UV radiation as well as outdoor elements and other corrosive forces, these amine curing agents are often used in high-end composite materials, outdoor coatings and decorative finishes.
