USE: Use as supplied

APPLICATION: Following the water rinse immediately after the blacking operation, the blacked component is immersed in a tank of dewatering oil for 10 minutes. Remove and allow 45 minutes to air dry. This procedure ensures that the water is removed from the surface of the component and establishes a protective anti-corrosive layer within the black coating. Ensure that the immersed component is suspended above any water which may accumulate in the bottom of the tank. This water should be drained periodically. Components, particularly those with blind holes, threads or porous surfaces should be rotated or agitated within the dewatering oil to ensure all the water is displaced and removed. Larger flat surfaces must be suspended vertically to facilitate run off of water.

To ensure that the dewatering oil is maintaining its efficiency, check treated components for streaks, discolouration or rust development all of which indicate that the product requires replenishment.

Keep the tank covered when not in use to prevent evaporation of white spirit. A tank in continuous use will require vapour extraction.
