What method of protection may be used for the transport/shipping of brass finished products?
A It is common to use a tarnish inhibitor prior to transporting brass components. These are based on benzotriazole. One such product is Armagard produced by a UK company, Armack Chemicals. Hot water is added to the Armagard and the component is dipped into the solution, then flash dried. Components are then wrapped in acid free paper. No standards relate to this process.
