Henkel BONDERITE® M-CR 1000™ AERO Light Metals Conversion Coating
Henkel BONDERITE® M-CR 1000™ AERO (formerly known as Alodine® 1000) Liquid chemical used to produce a protective coating on aluminum and aluminum alloys. The coating provides protection for aluminum and this coating provides an excellent bond for organic coatings. Develops a clear or colorless protective coating and it should be used when the characteristic aluminum appearance or finish must be retained. Approved for use under Boeing Specification BAC 5719 for Class B. Light metals
Use InstructionsOperating Summary
Chemical: ALODINE 1000 RTU
Bath Preparation per 100 Gallons: Used as receivedOperation and control:
Apply the coating chemical as suggested above.
Time: 1-3 minutes
The complete process normally consists of the following steps:
The work, after drying, is ready for use either painted or unpainted.
ALODINE 1000 RTU
Acid-resistant (rubber, stainless steel, or plastic) buckets, troughs, or other suitable containers are used to hold the coating chemical solution. Lead, glass, tin or galvanized iron should not be used. Storing the solution in mild steel containers will result in the decomposition of the solution and is not recommended.
NOTE: ALODINE 1000 RTU saturated rags, sponges, swabs, etc., should be thoroughly washed with water before allowing to dry or discarding. Otherwise, they may constitute a fire hazard.
Cleaning: All metal to be treated with the processing solution must be free from grease, oil and other foreign material before treatment. A complete line of cleaners is available. Our representative will recommend the proper cleaner.Water Rinsing: After cleaning, the metal must be thoroughly rinsed with water or wiped off with clean, water-damp cloths prior to coating with ALODINE 1000 RTU coating chemical.
Treating with the ALODINE 1000 RTU Processing Solution
Apply the coating chemical solution liberally to the aluminum surface. Treat only as large an area at one time as can be conveniently handled with the equipment being used (approximately 6 to 10 square feet of surface).
Use as many applications as necessary to get the coating desired, allowing approximately one minute reaction time before the application and before the final water rinsing. The color of the coating will range from clear to a light iridescent gold color depending on the aluminum alloy, temperature and number of applications.
Time: 1 -3 minutes
Rinsing and Drying: Excess coating chemical solution should be removed by either of the following methods:
Any seams, joints and crevices should be blown dry with clean, dry, compressed air and the moisture splatters wiped dry with clean rags.
This chemical should be stored indoors away from alkaline and organic materials. The freezing point of ALODINE 1000 RTU is 30° Fahrenheit.
Waste Disposal Information
Applicable regulations covering disposal and discharge of chemical should be consulted and followed.
Disposal information is given on the Material Safety Data Sheet for the product.
The solution is acidic and contains hexavalent chromium and fluoride. Waste treatment and neutralization may be required prior to discharge.
When handling the chemical products used in this process, the first aid and handling recommendations on the Material Safety Data Sheet should be read, understood and followed.
The product when used as supplied contains chromic acid in excess of 0.1 percent. The following statement, or one similar to it, should be included as part of the process tank labeling [29 CFR 1910.1200 (f) (4)].
POSSIBLE CANCER HAZARD, CONTAINS CHROMIC ACID WHICH MAY CAUSE CANCER BASED ON ANIMAL DATA. Risk of cancer depends on duration and level of exposure.
