Type III - Soft film (Avionic grade)
Grade 134a - Hydrofluorocarbon (HFC) propellant.
Intended Use MIL-PRF-81309:
The ultra-thin film, corrosion preventive compound covered by this
specification is intended for use on any metal surface. MIL-PRF-81309 can be used both for initial protection during shipment and storage and for in-service treatment. It should not be used around liquid oxygen fittings.
The ability of MIL-PRF-81309 Type III, class 2, grade 134A to prevent corrosion and to displace water and its ease of application when packaged as class 2 (self-pressurized containers) make it particularly suited for service use.
The combination of properties of MIL-PRF-81309 provide the necessary requirements for a corrosion preventing compound for use in the extreme naval aviation environment.
MIL-PRF-81309 is intended for indoor protection and short term protection outdoors where surfaces can be recoated when required.
This material is not intended as a substitute for other corrosion preventatives specified for protection of surfaces for periods of more than one month.
