Rust-Shield® VCI* Foam
Product Information Sheet
Type RS 300
How Rust-Shield® Works:
How Rust-Shield® Containing VCI* Works: Rust-Shield® is a polyethylene foam containing VCI*. VCI* or volatile corrosion inhibitor compounds vaporize from the Rust-Shield® foam. They are attracted to the charged surface of the metal by virtue of their polar orientation.
The VCI* molecules align on the surface of the metal to a depth of 3 to 5 molecules. This layer of molecules passivates the charged surface and creates a barrier that prevents oxidation. The corrosion cell (the flow of electrons in the metal and the flow of ions in the electrolytic surface layer) is unable to establish itself and corrosion is halted.
Airtight packing is not required!
Simply store or ship metal parts in a closed package together with Rust-Shield®. When the parts are unwrapped, the protective molecular layer immediately begins to dissipate. The metal parts are clean, corrosion-free and ready to use. No washing, dipping or cleaning is necessary.
Protective Packaging:
Rust-Shield® RS 300
is especially suited for cushion packaging applications, interleaving,
tool displays and instrument protection. It is also suited for the
marine industry for positioning fish hooks and tool storage. It can
be used anywhere there is a need to protect against rust and/or damage
from impacts.
