Alodine® 1200 is a two package chemical used to produce a protective. coating on aluminum which ranges in color from light iridescent golden to tan. The process is operated at room temperature. The coating produced minimizes corrosion and provides an improved bond for paint.
How does chem film work?
Chem Film, sometimes called by the trade names Alodine or Iridite, is a chemical conversion coating that is used to passivate aluminum. It protects aluminum substrates from corrosion and serves as a base for organic coatings while leaving dimensions unchanged. Chem Film is applied by dipping, spraying or brushing.
What is alodine 600 used for?
ALODINE 600 is a powdered chemical used to produce a chromate conversion coating on aluminium and its alloys, which ranges in colour from light, iridescent golden to tan. This product does not contain complex cyanides. It is particularly recommended where a low dielectric resistance coating is desired.
What is the purpose of alodine?
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.Is alodine a primer?
Aluma-prep is an etch, so is alidine, Alodine is Chromic acid, When the surface has already been etched, it does not need a self etching primer. Yes it will form an artificial Hydroxide coating to protect the aluminum.
Does chem film add material?
In order to make the metal more acceptable for use, chemical films are often applied to the metal, which improves corrosion resistance and contains the material as much as possible.
Is Chem film the same as 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.
How do you use Bonderite?
Activate by holding the applicator tip down on the surface to be treated. Press the pen tip down for 15 to 30 seconds to open the spring valve allowing BONDERITE M-CR 1132 AERO to wet the applicator tip. When the BONDERITE M-CR 1132 AERO just wets the tip, release the downward pressure. The unit is ready to use.How do you use alodine?
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. The work, after processing and drying, is ready for use either painted or unpainted.
Is alodine toxic?Yes, alodine is a dangerous compound and should be handled carefully. … The compound contains chromium, which may cause allergic reactions. Exposures in large quantity may lead to kidney damage, failure and eventually death. If swallowed this product can cause corrosive damage to the gastrointestinal tract.
Article first time published onHow do I use alodine 600?
Apply the Brush Alodine 600 to the surface by brush or swab. Do not apply by spray-gun or any equipment which atomises the solution into the atmosphere. * Scotchbrite is manufactured by 3M company. Always apply evenly and liberally, working upwards on vertical surfaces.
What is the difference between alodine 600 and 1200?
Color: Light Iridescent Gold to Tan, depending on aluminum alloy. The differences seen are that the #600 can be applied by an immersion dip, while the #1200 is applied by spray. A toner is used with the #600 and not with the 1200S I hope this helps.
What is the difference between alodine 1200 and 1201?
Alodine 1200S is a powder, chromate conversion chemical which must be dissolved in water to make a bath, which is then used to chromate aluminum. … 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.
What is alodine finish?
Alodine finish is a chemical conversion coating used for metals, particularly aluminum, to improve its resistance to rust and corrosion.
What color is alodine?
Alodine is a slightly cheaper process than anodizing, though it is more prone to scratches, wear, and cosmetic damage. The most common color of the coating is an iridescent greenish-gold, and thus it may also be used for cosmetic purposes.
How do you remove alodine coating?
Very fresh chem-film (Alodine, Iridite, chromate conversion coating) can be softened with 50% nitric acid, then wiped from aluminum [credit Max Stein & Brian Terry].
What is the difference between anodized and chem film?
While chem film treatments do add a thin layer of the chemical to the surface of the metal, anodizing tends to add a thicker layer of oxides. … Typically, chem films increase adhesion while anodizing doesn’t. One major benefit of anodizing compared to chemical films is that it comes in many colors.
Can you chem Film stainless steel?
Available coating types include polyurethane, enamel, epoxy, and thermal barrier coatings designed for protection and adhesion to materials such as steel, stainless steel, aluminum, brass, copper, or titanium.
Is chem film the same as anodizing?
Anodize vs Alodine (Chem Film) Because the name sounds a bit like anodize, there is sometimes confusion between the two coatings. While both are conversion coatings, chem film is much thinner than anodizing and is alsocreated by immersion but without use of electrical current.
Does alodine work on magnesium?
Bonderite (Alodine) 5200 Conversion Coating for Aluminum and Magnesium. Alodine 5200 is a chrome-free and environmentally friendly conversion coating. This coating is commonly used on castings, forgings, wrought alloys of aluminum, magnesium, and titanium.
Can you alodine titanium?
Titanium can be anodized. See, for example, AMS 2488 [affil. … It certainly isn’t aluminum or any non-ferrous metal, so we simply assumed that it had to be steel or titanium. Whatever the case, they are anodizing it and not using Alodine/primer coating.
Does alodine work on steel?
Chromate conversion coating or alodine coating is a type of conversion coating used to passivate steel, aluminium, zinc, cadmium, copper, silver, titanium, magnesium, and tin alloys.
Can you spray alodine?
Alodine can be sprayed, brushed, or sponged onto large surfaces. The surface must remain wet for several minutes or until a light to dark golden brown develops. Alodine should not be allowed to dry on the surface because of the salts it contains.
How do you use alodine 1001?
Operating Summary: Brush Application: Dilute one part ALODINE 1001 with one part water. Immersion Application: For each 100 parts of bath, add 25 parts ALODINE 1001 to 75 parts of water.
How do I use Alumiprep?
For light oxidation and corrosion removal dilute one part TURCO ALUMIPREP 33 with five parts water. For heavy oxidation and corrosion removal dilute one part TURCO ALUMIPREP 33 with two parts water. Immersion Application: For each 100 parts of bath, add 25 parts of TURCO ALUMIPREP 33 to 75 parts of water.
What is the difference between alodine and anodize?
The primary difference between Alodine (chem film) and anodizing is that anodizing is an electrolytic process and Alodine (chem film) is not. Alodine (chem film) and anodizing are both processes used in aluminum finishing to improve corrosion resistance. Both transform the outer layer of the surface of the metal.
What color is MIL DTL 5541 3?
This film typically appears to be gold or brown in color, but in some cases may be optionally specified as having no color (Having no color is described as “clear”). Type 2: Addresses compositions containing no hexavalent chromium.

What is the difference between Iridite and alodine?
A. Iridite is a trade name for a whole family of chromate conversion coatings. Alodine 1200S is the trade name for aluminum chromate that meets MIL-C-5541. Iridite 14-2 is the particular trade name for a product that is chromate conversion for aluminum.
What is the use of chemical conversion coating?
Chemical Conversion Coating is used to protect enclosures and metal parts from corrosion, and to ensure that reliable electrical connections can be made to aluminum chassis and components. It is also an effective pretreatment for powdercoat.
What does conversion coating do?
Conversion coating is a type of coating used on metals in which the surface that is covered is turned into a coating with electrochemical or chemical processes. In addition to corrosion protection, conversion coating also offers enhanced surface hardness. It also can be used as a decorative primer.
