Is alodine 1200 conductive?
Alodine 1200S conforms to MIL-C-5541E Class 1A and 3 coatings, Methods A, B & C application. Alodine coatings are electrically conductive.
Is alodine 1201 conductive?
High-adhesion surface preparation for paint. Improves corrosion resistance. Preserves electrical conductivity of surface. No change in dimensions.
What is the difference between alodine 1200 and 1201?
Alodine 1200 is intended as an immersion treatment. Controlled in a bath at elevated temperatures. Alodine 1201 is a brush application treatment.
What is the difference between alodine 600 and 1200?
The primary difference in the two chemicals is the issue of coating weight. The Alodine 1200 will produce a heavier film than the 600 will. The Aerospace industry uses the 600 chemical on areas that require electrical bonding.
What is the difference between alodine 1200 and 1200S?
Alodine 1201 is similar to a 20 gram per liter solution of Alodine 1200S. The AL 1200S can be used anywhere AL 1201 is used, but for large amounts of touch-up work or if handling of a liquid is preferred, AL 1201 is more convenient.
Does alodine work on magnesium?
Alodine 1201 is for aluminum and will not properly pretreat magnesium.
Why do you alodine aluminum?
Chem film or Alodine is a chemical conversion coating that’s mostly used to protect aluminum from corrosion. It’s primarily used to passivate aluminum as it protects this metal and serves as a base for paint coatings. It leaves aluminum unaffected, so it’s easier to put paint over it without changing anything.
How do you mix alodine?
PREPARATION OF ALODINE SOLUTIONS Mix 22.5 grams of Alodine 600 with each litre of water. Stir well until the powder is dissolved. Note: A small amount of insoluble material may settle out of solution; this can be disregarded.
How do you apply alodine?
Apply ALODINE 1201: Buildup: For brush application, ALODINE 1201 is applied to a chemically cleaned surface using the solution undiluted. For immersion application, ALODINE 1201 is diluted by mixing 33 parts of ALODINE 1201 and 67 parts of water for each 100 parts of bath volume required.
Does alodine work on steel?
“Alodine” is a Henkel trade name for their line of chromate conversion coatings for aluminum and light metals. A. Hi Joseph. No, chromate conversion coating is not applicable to bare steel, although steel may be zinc plated and then have a chromate conversion coating applied.
How do you apply alodine to aluminum?
APPLICATION OF ALODINE Apply the diluted Alodine liberally to the aluminium surface. Treat only as large an area at one time as can be conveniently handled with the equipment being used (approximately 6-10 square feet of surface.)
How thick is alodine coating?
0.00001-0.00004 inches
Aluminum chromate conversion coating/alodine produces a thin coating in the range of 0.00001-0.00004 inches (0.25-1.0 µm) in thickness. Chemical conversion coatings on aluminum are amorphous in structure with a gel-like composition hydrated with water.
How long should alodine sit?
Normally, 1-5 minutes is required for coating formation.
How long do you leave alodine on aluminum?
Allow the Brush Alodine 600 to act on the surface until an iridescent golden to golden yellow coating is obtained. This will take 3-6 minutes depending on the activity and temperature of the surface.
What is the purpose of alodine?
What is Alodine®? Also known as chem film or chemfilm, Alodine® is a chromate conversion coating that protects aluminum and other metals from corrosion. Related products include Iridite®, TCP-HF, and Bonderite®. The process of applying a chromate conversion coating is referred to as chromating.
Why is alodine used?
How is alodine applied?
How long does alodine last?
Alodining is a process in which a metal is coated with a chemical called alodine. This coating hardens to the surface and can last for years if painted, not requiring reapplication.
What is the purpose of alodine on aluminum?
Can alodine be removed?
The unit has been is service for several years and the desire is to “clean” the aluminum on the part an put it back into service. The unit cannot be stripped and re-Alodined because foam padding is on it in several locations. Mild solvents such as water, Isopropyl Alcohol [affil.
