ZERUST®/EXCOR® AxxaCoat™ 90B HFS is a sprayable high-flash outdoor rust-preventative coating designed to protect metal parts and assemblies during long-term indoor and outdoor storage and challenging overseas shipping applications where a tough yet removable coating is essential.



  • Effective corrosion protection where traditional anti-corrosion methods cannot be used
  • Easy to apply, economical to use
  • Suitable for new equipment and to protect the reliability of existing equipment
  • The fully cured coating is temperature resistant up to 300°F (150°C)
Product Description

Product Description

Use AxxaCoat™ 90B HFS to safely protect machinery, equipment, other large metal assets, and more for up to 2 years when stored outdoors or for many years when stored indoors. For large surface applications that require protection, such as storage tank walls, pipelines, building infrastructures, bridges, etc., ZERUST® AxxaCoat™ 93 Series is recommended.

When used indoors, AxxaCoat™ 90B HFS coating dries to form a slightly tacky, matte black film. However, when used outdoors and exposed to solar radiation, the outdoor rust preventative coating will cure to a hard, dry-to-the-touch, matte black film. Additionally, once the metal asset is ready to be put back into use or service, the coating may be removed with mineral spirits or kerosene. For an optimal corrosion management solution tailored to your metal assets, we encourage consulting with a ZERUST®/EXCOR® representative.
