Benefits of Dichromate Seal
The sealing process coats the anodized aluminum surface and reduces its porosity. This provides many benefits, including:
- Enhanced corrosion resistance: Chemical treatment provides superior resistance to corrosion from environmental factors such as industrial pollutants, moisture, and salt.
- Improved adhesion: It also enhances the adhesion of finishes such as paint to the anodized surface.
Aerospace, defense, and military industries rely on dichromate seal to bring these benefits to anodized surfaces.
Applications
Dichromate seal is a preferred finish for anodized aluminum used in many aerospace, and military applications, including:
- Guarding internal aerospace components, fuselage assemblies, and wings from harsh environments and high altitudes
- Providing corrosion resistance to military communications devices, vehicles, and weapons
Dichromate seal meets military specifications of MIL-A-8625 for paint adhesion and corrosion resistance.
