 Black Oxide Powder

GENERAL DESCRIPTION: Black Oxide Powder is a special formula developed for applying a black oxide coating to steel. This process is also known as "Bluing."

PROPERTIES:

Form: Powder
Density: N/A
Flash Point: None
Phosphates: None
Stability: Stable
pH: Highly alkaline

USE PROCEDURE: Dissolve Black Oxide Powder into water while heating the solution until the solution temperature reaches 285°F to 295°F. Dip time is approximately five minutes but may be longer. The ability of Black Oxide to apply a "bluing" to steel is temperature dependent. As the temperature falls below 285°F more product must be added. As the temperature rises above 295°F water must be added. Cast iron parts blacken best at 285°F, while steel parts blacken best at 295°F.

Prior to the black oxide process, parts should be cleaned and thoroughly rinsed to ensure that the work is properly prepared. After the oxide process is complete, parts should be rinsed in a roiling boil, clear water rinse to remove the excess chemical. If desired, parts can then be dipped in a water displacing corrosion inhibitor, Metgard WDS, for maximum corrosion protection.

SAFETY DATA: Contains sodium hydroxide. Avoid contact with skin and eyes. DO NOT INGEST. When handling, wear rubber gloves, goggles and any other appropriate equipment or clothing to avoid skin contact. Avoid contact with clothing. Should contact occur, flush skin with water; for eyes, flood with large amounts of water for 15 minutes and get medical attention. If ingestion occurs, DO NOT INDUCE VOMITING. Drink fruit juice, milk or vinegar and get medical attention immediately. Read the Material Safety Data sheet before using.
