ACF-50

Aircraft Corrosion Protection, ACF-50

Aluminum corrodes almost immediately forming an oxide layer that will protect it from further corrosion. For example: Place an aircraft in a salty environment near the ocean and the unprotected aluminum corrodes if not handled or pretreated properly.

There are a number of ways one can protect an aircraft against corrosion: painting, waxing, zinc-chromate priming, thin layer of pure aluminum (Alclad), anodizing and coating with a liquid protective solution.

Another fluid solution against corrosion is made by Lear Chemical Research Corporation. It is called ACF-50 and has been used for years in the aviation, motorcycle and powersports industries.



Anti-Corrosion Formula-50

ACF-50, Anti-Corrosion Formula, is a state of the art, anticorrosion/ lubricant compound that has been specifically designed for the aerospace industry. It can be described as an ultra thin fluid film compound which must be applied on a biannual basis.

Surface treatment

ACF-50

ACF-50 actively penetrates through the corrosion deposits to the base of the cell where it emulsifies and encapsulates the electrolyte, lifting it away from the metal surface. This is in contrary to other wax like product that encapsulate the oxidation and the moisture.

This moisture is then dispelled and at the same time a barrier is provided which prevents any further moisture penetrating the metal, thereby keeping the oxidation cell fully inactivated.

This product continues to actively penetrate and creep into the tightest of seams, lap joints, micro-cracks and around rivet heads, dissipating the moisture, even salt water, in these corrosion prone areas. These unique abilities makes sure that the effectiveness is about 24 months, gradually disappearing as it is chemically consumed.

ACF-50

With an active thin fluid film chemistry (TFFC) it will penetrate corrosion deposits where it chemically emulsifies and displaces the electrolyte. This isolation process keeps the corrosion cell fully deactivated.

The product also designed with the professional aviation technician in mind. Keep in mind that it should be used within the guidelines established by the OEM or governing agency for the prevention, control, or repair of corrosion.

Barrier

ACF-50

On new metal it forms a self healing barrier that prevents corrosion from starting. It will remain physically and chemically effective for up to two years (24 months).

It is important to emphasize that ACF-50 is also an excellent lubricant but does NOT contain any wax, resin, silicon or Teflon... compounds that can gum up mechanisms, block drain holes, or trap moisture to cause corrosion.

Other Applications

Although ACF-50 is used primarily in the aviation industry it can be used virtually anywhere where corrosion is expected to be a problem. Applications such as interior metal surfaces, structural assemblies, micro switches, avionic components, solenoids/motors, battery terminals etc. are all valid.

ACF-50 is qualified under Mil-C-81309E, and manufactured under ISO 9000 certified processes. ACF-50 holds written OEM approvals from: Gulfstream, Bombardier, ATR Regional Transport, Douglas/Boeing Helicopter, Bell/Textron, Robinson, Enstrom, Sikorsky, MD Helicopters, Schweitzer, Hiller, British Aerospace, Concorde Battery, Raytheon, Piper, Cessna, Pilatus, Beech, Van's, Extra, Air Tractor, Lake, Rolls-Royce, Britten-Norman, Learjet, McDonnell Douglas, and Canadair.

Viking Aircraft Engines (FL, USA) also uses ACF-50 to protect their Honda engines from corrosion.
