Alodine (Alocrom 1000)

Alocrom 1000 produces protective coatings on aluminium and its alloys without significantly changing the appearance of the aluminium surface. It is recommended where a very low surface electrical resistance is required or the aluminium is to be subsequently lacquered and so the surface must be uniformly metallic. Paint adhesion to this coating is excellent, and the electrical resistance is lower than either Alocrom 1200 coatings or untreated alloy. Some key features include:

• Best electrical conductivity of all Alocrom conversions.
• Minimal change in surface appearance: maintaining metallic appearance.
• Improved adhesion and corrosion resistance for painted surfaces.
• Coatings are integral with the metal and will withstand bending and denting of the surface.
• Gives excellent protection against corrosion to both painted and unpainted aluminium surfaces.
