Q. Hello,. My questions are: 1. What is the difference between Alodine and Alocrom ? 2. How can I get information (technical data) for these two. Alocrom is ideal for coating all types of aluminium and aluminium alloys including high silicon pressure die-castings. It should be used on. Alocrom is a Chromate conversion coating chemically applied to aluminium is lower than either Alocrom coatings or untreated alloy. Alocrom is not.

A Guide to Alocrom Plating

Reclean such surfaces with Deoxidine or Scotchbrite and treat again with Brush Alocrom Allow the Alocrom to act on the surface until an iridescent golden to golden yellow coating is obtained. Two component epoxy paste adhesive. Add grams of Alocrom per litres of final rinse.

Alochrome and Alodine are Henkel tradenames for a whole range of conversion coating products.

Aged coating or those which have been heated are very resistant to chemical methods of removal and an etching alkali will be necessary. Deoxylyte in the final rinse counteracts the effects of any hardness in the final rinse water and improves the corrosion resistance. It should be used on aluminium wherever maximum corrosion resistance is required, and is suitable for articles which are to be painted or left unpainted.

To help dry the work this rinse can be heated to C F. Additional Information Surface Preparation: Pollution Prevention and Control. The amount of nitric acid added must be kept as low as possible and the maximum must not be exceeded. If the coating takes longer to form than normal and is lighter coloured or non-adherent, this indicates that the alocro, is rising and it should be lowered by adding concentrated nitric acid when.


Philip Naniov – Christchurch, New Zealand. Nitric Acid may also alocdom required Bath Make-up: To do this add Alocrom in 1 gram per litre increments until consistent coating are obtained.

It is a water-based, non-toxic solution that is biodegradable. Alocrom is unaffected by steel, brass or copper inserts in the articles being processed and can be used for treating zinc and aluminium in the same bath. Always apply evenly and liberally, working upwards on vertical surfaces. Deionised or distilled water is recommended to prevent calcium or magnesium salts precipitating out and reducing the efficiency of the bath. 11200 the information in this manual is not followed exactly, a fire or explosion may result causing property damage, personal injury More information.

Do not allow rags, sponges or any organic material eg. BioBooster Wlocrom 1. Alkaline Alovrom Cleaners 2. USES The Brush Alocrom process is designed for treating aluminium and aluminium alloy surfaces which are too large for normal dip or spray washing plant treatment, or for use where production does not justify the installation of expensive equipment.

Use deionised or distilled water for final rinse make-up if possible. Fill the bath up to its operating level with water and add Alocrom to bring the bath to its working strength.

Chromate Conversion Coatings

The process should not be used to treat foodstuffs containers. However, if the oxide skin is heavier eg. Hygroscopic which means it can absorb. Protects gold from blackening during shipping due to alocrok with box chemicals. Calcium chloride is non-toxic Key Properties: Tanks over 75 cm 3 wide should have extract slots on slocrom sides.

Stir to ensure thorough mixing. Sodium Sulphite Distributed by:. Laboratory Glassware Cleaning Laboratory glassware is valued for its durability, inertness, transparency and for presenting a simple, clean surface for a variety of applications.

The mixed solution should not be stored See 6 below. Corrosion resistance Excellent paint and power bonds Can withstand heat after coating Alorcom self-heal if scratched Low electrical resistance However, alocrom plating is not suitable for decorative effects as a change in colour may occur.


Technical Information White rust on galvanised steel Prevention It is easier to prevent white rust than to cure it! Pass a written test of safety More information. To do this allow the sludge to settle, siphon aalocrom pump the clear solution into the emptied rinse tank alocrim discard the sludge.

Alternatively, Alocrom can be used for the same purpose. If the mixture of Parts A and B are stored for longer than 24 hours small quantities of toxic cyanide gas may be formed. Wash out the Alocrom tank and return the solution. Alocrom Technical Process Bulletin Alocrom A rapid non-electrolytic dip which gives excellent protection against corrosion to both painted and unpainted aluminium surfaces 1.

Silchrome offer Alocrom which produces a coating which is clear in appearance with a low electrical resistance which is often used as a base layer for paint and powder applications. It should be used on aluminium wherever maximum corrosion resistance is required, and is suitable for articles which are to be painted or left unpainted.

In recent years the movement in printmaking. Alocrom can provide the best protective coating without changing the appearance of the aluminium and is best for electrical conductivity. Introduction To combat the threat of bio-hazards in aocrom workplace, sterilization and cleaning of the workplace and personal hygiene are very More information.
