BLACK F-1401
For Ferrous Metals |
|
Black -F-1401 is a concentrated, rapid acting chemical conversion
liquid compound for blackening Steel and Ferrous Metal parts by Immersion
at room temperature. The product is a mildly acidic solution containing
no chromates, sulfides, cyanides, caustic or Phenols.
Preparation of the Black -F Solution:
Use an acid resistant container as the Immersion tank.
Plastic, plastic lined, glass or rubber lined are suitable. Do not use
an uncoated metal container. Black F-1401 concentrate should be diluted
with 9 parts of water (10% to 90% of water by volume). Determined by
tests usually a period of 10 to 60 seconds is needed to produce an uniform
black finish. The Immersion time can be shortened by using a stronger
solution or lengthened by using a weaker solution. Black F-1401 is not
designed to clean surfaces. For good results, parts must be free of
oil and rust.
Preparation For Blackening and Sealing:
- Clean the part with Cleaner 104.
|
- Rinse with over flowing cold water.
|
- Immerse the parts in Black-F-1401 solution for
10 to 60 seconds. Agitate the parts to break air bubbles and
to assure solution contact with all surfaces. Plastic or plastic
lined baskets should be used for small parts.
|
- Rinse thoroughly with over flowing cold water to stop the chemical reaction.
|
- It is recommended that a protective lacquer, Trilac 747 or WSL-55 (clear or black, water soluble) be applied to the coating to provide maximum life.
|
- Parts can be immersed in a water-soluble lacquer
while still wet from the preceding rinse, or can be sprayed
or sealed. Black-F finish in itself imparts very little corrosion
resistance to the Aluminum surface. However, its crystalline
structure is porous and will absorb the sealant or lacquer,
promoting long-term corrosion resistance.

Solution Control
The blackening process with Black F is a chemical reaction
between the solution and metal surface. Chemical activity is gradually
diminished as the solution is used but may be restored to the desired
strength by adding fresh concentrate. When Immersion time necessary
to produce the desired black is increased, add sufficient concentrate
to reduce Immersion time to your previous standard. Keep a record of
additions to establish a bath history.
Caution:
Black F-1401 concentrate and the process is mildly acidic.
Precautions for handling this type of material should be observed (corrosive).
Avoid contact with skin and eyes. Use protective clothing (aprons, face
and eye shields, rubber gloves) when handling chemical material. In
case of contact with skin, flush area with large amounts of water; for
eyes, flush with large amounts of water and get medical attention. The
solution should be considered toxic if taken internally!
