What does amine blush look like and how can it be identified on surfaces?

Amine blush is a waxy or greasy film that can appear on surfaces after using certain epoxy resins. It is often transparent or slightly yellow in color and can feel sticky to the touch. To identify amine blush on surfaces, you can wipe the surface with a clean cloth dampened with water or isopropyl alcohol. If the cloth picks up a greasy residue, it is likely amine blush.
