• Zerust Vapor Capsules and storage bags can be used in any environment with no measurable chemical interaction with other elements. There is no likelihood that the vapors will enhance flammability, or react with industrial or marine atmospheres to create any by-products.
  • You may combine Zerust packaging materials to ensure maximum corrosion protection.
  • Zerust products are stable under normal storage and packing conditions. However, avoid contact with flames, strong acids, solvents that swell polyethylene, oxidizers and reducing agents that can react with the internally contained chemical system.
  • Zerust Vapor Capsules will not provide protection from corrosion caused by direct contact of the metal with acids, water, etc.

  • Do not install Zerust products where they will come in contact with bulk water or be submerged.
  • Pack only clean and dry parts.
  • When storing sensitive components, wear gloves to avoid leaving acidic, corrosion causing fingerprints.
