Q. Is ACF-50 approved by the US Government?
A. Yes ACF-50 is US Government performance qualified to Mil-C-81309E, Type II
class I.
Q. Does ACF-50 meet any other aerospace industry standards or have any OEM
approvals?
A. Yes ACF-50 meets aerospace anti-corrosion requirements for many OEM’s; AIRBUS,
BOEING, DOUGLAS and others, see the reverse side of this document for a complete listing
as well as additional OEM recommendations.
Q. How long has Lear Chemical been producing Thin Fluid Film anti-corrosion compounds
and how long has ACF-50 been in the marketplace?
A. Lear has twenty five years experience as a chemical manufacturer and ACF-50 has an
excellent fourteen year track record as a product used by industry professionals who want
performance they can trust.
Q. Is ACF-50 Toxic?
A. No. Complete toxicology tests (oral-eye-dermal) have been performed on ACF-50 by world
renowned Hazelton Laboratories. Their testing concluded that ACF-50 is Non-Toxic according
to EPA and OCED standards.
Q. What does the FAA think about ACF-50?
A. 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).
Q. Does ACF-50 meet US State requirements for Volatile Organic Content (VOC)?
A. 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.
Q. How often does ACF-50 need to be applied to the airframe?
A. We recommend a minimum of once every two years. Shorter or longer intervals will be prescribed
depending on the aircraft’s operational environment.
Q. What type of equipment do I need to apply ACF-50?
A. 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.
Q. Does ACF-50 loosen rivets?
A. 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.
Q. Will ACF-50 harm aircraft plastics, paint, or wiring?
A. 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.
ACF-50 “the Professionals Choice” gives you the peace of mind that your investment is receiving the best possible protection.
