Henkel Alocrom 1200 is available in brush-on and dip varieties and forms a gold-coloured protective coating on aluminium and aluminium alloys. The protective surface created is integral, and so will flex with the metal under load, and provides excellent corrosion resistance for both painted and unpainted finishes.
Alocrom 1200 Dip formulation requires only a short immersion time – a few minutes at room temperature – to create the protective coating. Alocrom 1200 Brush formulation requires no specialist equipment or training and can be applied by brush or swab. Air drying is suitable for either application.
Alocrom 1200 is a versatile treatment for industrial and electrical components, vehicle parts including body panels, domestic appliances, and aircraft components. It is approved to DEF STAN 03-18 for use in aircraft (Certificate 031801), including specific approval for repairing damaged anodic coatings. It is useful where maximum corrosion resistance is required.
The Alocrom process can be applied to aluminium and aluminium alloys including high silicon pressure die-castings. It is not is affected by steel, brass or copper inserts and can be used for treating zinc and aluminium in the same bath. It should not be used for decorative effects on unpainted alloys exosed to exterior weathering, since some colour change may occur.
Brush Alocrom 1200 is supplied as two liquids – Parts A and B – which are mixed together before application. Detailed advice on appropriate handling and storage is provided on the product data sheets.
These products are sold in the UK under the Alocrom brand name, and are known in other territories under the Alodine name: Alocrom 1200 and Alodine 1200 are identical products.
