Notes
Carbohydrazide also passivates metals and reduces metal oxides converting ferric oxide to ferrous oxide and converting cupric oxide to cuprous oxide.
Carbohydrazide reacts directly with oxygen. It helps prevent oxygen damage and continues to passivate metal surfaces during wet lay-up. Carbohydrazide can also be used as a curing agent for epoxide-type resins.
