Amine Blush

Definition - What does Amine Blush mean?

Amine blush is the occurrence of dichroism with little opacity that is formed on epoxy films due to the interaction of a co-reactant, carbon dioxide and water, which results in amine carbamate as a product.

Corrosionpedia explains Amine Blush

Amine blush appears as a waxy layer on any substrate surface. As such, it can be a problematic occurrence that interferes with corrosion prevention methods. It prevents the adequate adhesion of a protective coating to a metallic surface that is prone to corrosion.

Amine blush is water-soluble; therefore it is easily removed with warm water.
