concluded that ACF-50 is Non-Toxic according to EPA and OCED standards.
- What does the FAA think about ACF-50?
Answer:While the FAA is not in the habit of providing general approvals they do have at least two criteria for accepting a product. Their primary
method for acceptance is for an OEM to list the product in their aircraft maintenance manual. The second method is for a product to meet a Mil-Spec. Since
ACF-50 meets both of these criteria the FAA finds ACF-50 an acceptable product as a general corrosion preventative for use on aircraft (letter dated Aug.
13/96).
- Does ACF-50 meet US State requirements for Volatile Organic Content (VOC)?
Answer:Yes ACF-50 is VOC compliant in all fifty states. ACF-50’ s VOC content is well below the tough air quality control regulations in California.
- How often does ACF-50 need to be applied to the airframe?
Answer:We recommend a minimum of once every two years. Shorter or longer intervals will be prescribed depending on the aircraft’ s operational environment.
- What type of equipment do I need to apply ACF-50?
Answer:The most economical way to treat an airframe is with our specially designed spray system. Its light weight, compact size, ergonomic design,
and aircraft quality construction provides for efficient product usage and minimal labor investment. The system works on 40 psi. @, 4 to 5 CFM.
- Does ACF-50 loosen rivets?
Answer:No. ACF-50’ s low shear formula will penetrate around a tight rivet removing moisture without causing it to loosen. Unlike other products
ACF-50 does not contain EP (extreme pressure) additives. The presence of these undesirable additives could cause rivets to loosen and faying surfaces to
loose their structural cohesiveness.
- Will ACF-50 harm aircraft plastics, paint, or wiring?
Answer:ACF-50 was tested for stress crazing on acrylic plastic and for effect on aircraft grade paints with both tests showing no deleterious effects.
ACF-50 was tested on polyimide insulated wire and found to have no negative effects.
