ASHCROM G70

(Yellow Chromate Conversion coating for aluminium & its alloys)

 

Specn. MIL-C-5541

 

Our above product is in highly concentrated liquid form and with small quantity in water, it produces yellow conversion coating on aluminium which has better corrosion resistance and paint bonding.  It is used as a low cost substitute for anodizing and with additional desirable properties.  The process is very simple and easy to operate.  Yellow coating is produced in the ASHCROM-G70 bath by short time immersion at room temperature or by spraying or brushing.

 

The film thickness and colour can be varied by changing the bath concentration and treatment time.  The thinnest films are clear.  As the thickness increases, colour develops as a light yellow and finally medium brown.  The corrosion resistance and colour of chromated aluminium varies with alloy composition.  It depends further on film thickness.  High silicon alloys have much less corrosion resistance whereas copper alloys have better corrosion  resistance.  Common practice is to use chromate treatment plus a primer and a top coat to obtain a finish of  maximum protective value and durability.

 

Low electrical resistance makes chromate films highly suitable for many electronic application.  Ground connections can be made to treated aluminium chasis without removing the protective film.  Other parts such as booster nozzles, wave guides, connectors & aluminium cabinets, missile and other aircraft and military components can be chromated with this ASHCROM-G70 treatment.  This chromate coating is conductive in nature.

ASHCROM-EL

(Chromate Conversion Green Coating for Aluminium by cold immersion)

ASHCROM-EL is of acid chromate type chromating chemical with activators and brighteners. It is recommended for getting chromate conversion coating of aluminium. The film produced is composed of amorphous tri and hexavalent chromium, free from pores and about 0.00001 inch thick. Colour produced is irridescent greenish yellow to olive green depending on the alloy and processing conditions. The coating is harder than chromate film on zinc but considerably softer than anodized coatings. Abrasion resistance is good and corrosion resistance is superior to anodised films. It not only enhances paint bonding but also gives an attractive corrosion resistant finish. The chromate film so produced is non-conductive in nature.

USES :

The finish has attractive appearance combined with corrosion resistance, ability to cover up scratches and other blemishes which have occurred during the previous stages of manufacture and has resistance finger marking and capability of being spot or flame welded. It provides a satisfactory base for final paint finish and helps in increasing the life of paint considerably.

Specially for aluminium components used in the electronic industry it serves as a final finish with anti-corrosion properties.

APPLICATION :

1. Degrease the components with ASFOCLEAN-B using 5% solution in water in M.S. tank at 80°C to 90°C for 5 to 10 minutes depending on oil or grease.

2. Rinse with running water in M.S. tank.

3. Dilute ASHCROM-EL 10-20 times with water in PVC lined tank or polythene container and dip the cleaned aluminium components at room temperature for 5 to 10 minutes. ASHCROM Additive may be used at 0.5 – 1% based on the volume of the bath for darker coatings. It also helps in accelerating the process and maintain pH between 1.5 to 2.

4. Rinse thoroughly with cold water and then with hot water.

5. Dry at low temperature (60°C)

 

The ASHCROM-EL solution lasts for quite a long time and therefore, replacement cost is much less. Solution is quite stable with respect to pH. Excessive additions of ASHCROM Additive will give rise to powdery coatings.

PRECAUTIONS :

Use rubber gloves and aprons while working with this chemical. Avoid any splashes on skin. If ASHCROM-EL spills accidentally on Skin/Eyes wash with running water and consult physician if necessary.

 

PACKINGS : 6 Kgs, 12 Kgs & 35 Kgs.
