Diver Safe Grease
Agency / Branch:
DOD / NAVY
Submarine hangar areas have actuated parts (doors, hatches, etc.) that must be lubricated to ensure correct operation and long service-life. The Navy currently uses Termalene1/2, a hydrocarbon-based grease, for this purpose. Unfortunately, NAVSEA has found that Termalener off-gasses toxic compounds in pressurized environments, making it unsuitable for use in the enclosed and sealed areas encountered by divers during diving operations. For manned diving operations, the Navy currently uses Krytoxr 240AC or Halocarbon 25-5S, which are both based on fluorinated polyethers. These greases have excellent performance and do not release toxic chemicals. However, the resistance to seawater washout is low, and these expensive materials constantly have to be reapplied to ensure adequate lubrication. This constant expense is unacceptable to the Navy. TRI/Austin is proposing to develop a new diver safe grease based on combinations of fluoropolymer and hydrocarbon greases. The new grease will, at a minimum, provide the same lubrication properties as those currently used. Additionally, the grease will offer the same resistance to washout as Termalener, but will not off-gas any toxic chemicals, making it safe for use in sealed environments. The Navy can expect to save both time and money associated with the constant reapplication of the currently used materials.
