Aerospatiale SE 313/SA 318 Alouette II: ACF-50 Anti-Corrosion Formula

ACF-50 Anti-Corrosion Formula is a specialized chemical compound designed to prevent and stop corrosion on aircraft and ground support equipment (GSE). Using advanced polar bonding technology, it forms a protective barrier that displaces moisture and shields metal surfaces from further oxidation. ACF-50 is trusted by general aviation users, commercial airlines, military operators, and maintenance professionals worldwide.

ACF-50 penetrates deep into metal surfaces, pushing out moisture and preventing oxygen and corrosive agents from reaching the metal. It actively neutralizes existing corrosion by drawing out moisture and allowing it to evaporate. Additionally, ACF-50 provides light lubrication, reducing friction and extending component life by minimizing wear.

ACF-50 delivers multiple advantages for aircraft corrosion prevention:

• Protection of Investment: Minimizes long-term maintenance costs by protecting vital GSE and aircraft components.
• Enhanced Safety & Uptime: Helps maintain structural integrity and operational readiness by guarding against corrosion-related failures.
• Comprehensive Coverage: Forms a fogging mist that reaches tight, hard-to-access spaces like avionics bays, lap joints, and seams.
• Proven Performance: Known for superior penetration, long-lasting protection, and endorsements from major aviation organizations.

ACF-50 is safe for use on virtually all metal surfaces, both painted and unpainted, whether inside or outside the aircraft. It’s commonly applied to structural components, electrical connectors, avionics, battery terminals, hinges, and joints, as well as to exposed wiring and mechanical parts on ground support equipment.

Note: ACF-50 should not be applied to brakes, tires, or flight control surfaces where a dry, friction-based finish is required.

Yes, ACF-50 is fully compatible with powder-coated surfaces. Its nonreactive, noncorrosive formula won't degrade, discolor, or damage coatings, making it safe to apply across the airframe or on GSE. ACF-50 forms a protective film that helps prevent corrosion, even under or around coatings where moisture might seep into seams or joints. For best results, ensure powder-coated surfaces are clean and dry prior to application to promote maximum adhesion and long-lasting protection.

Absolutely! ACF-50 is widely used in marine, automotive, and industrial sectors. It protects motorcycles, boats, and machinery by preventing corrosion on electrical systems, hinges, and exposed hardware. Thanks to its nonconductive and nontoxic formulation, it’s safe for use in sensitive applications across a range of industries.

No, ACF-50 is nonflammable and safe for use in high-risk areas like fuel systems, avionics bays, and electrical panels. Its fire-resistant properties make it ideal for aviation and marine environments where safety is critical.

Yes, ACF-50 is designed with environmental responsibility in mind. It’s nontoxic and contains no chlorinated solvents, making it safer for both users and the environment when used as directed.

Apply ACF-50 to a clean, dry surface using a sprayer or brush, focusing on seams, joints, and exposed metals. Ensure thorough coverage, including hard-to-reach areas. Only a small amount is needed – overapplication is unnecessary. Allow it to dry before returning the equipment to service.

No, ACF-50 is designed to be highly durable and water-resistant. Once applied, it forms a moisture-repelling barrier that resists rain, salt spray, and harsh weather conditions. This makes it particularly effective for aircraft and GSE exposed to the elements.

ACF-50 provides long-lasting protection – typically 12 to 18 months in most applications. In low-exposure areas, such as interior components, it may remain effective for up to 24 months. Reapplication may be necessary more frequently in high-exposure zones. If water still beads on the treated surface, ACF-50 is still active.

Yes! ACF-50 is approved by more than two dozen airframe OEMs and complies with military and commercial aviation standards. The FAA recognizes it as a suitable corrosion-preventive compound, and it's trusted across the global aviation community for its effectiveness and safety.

When stored properly, ACF-50 has a shelf life of two years from the date of manufacture. To maintain its chemical integrity and performance, keep it in a cool, dry location away from extreme heat or direct sunlight.
