Our team at Chip’s Custom Painting only uses the best pretreatment on the market for our clients’ aircraft.

PreKote, a surface pretreatment, is one of the newest and best ways to treat and prevent corrosion.

“PreKote is a non-chrome surface pretreatment product and is free, ODS free, odor free, and readily biodegradable upon disposal.” (1)

Used by many commercial aircraft companies such as SouthWest Airlines, AirCanada, United, FedEx, UPS and the U.S. Air Force, PreKote offers “superior adhesions, improved paint flexibility and advanced corrosion protection on painted surfaces”. (2)

There are several types of corrosion found on aircraft, and we’ve listed a few below: (4)

Uniform Surface Attack: The most common type of corrosion and is caused by exposing the metal to oxygen in the air.

Intergranular Corrosion: Usually seen on 7000-serios alloys, it is difficult to detect and usually once found, the metal needs to be replaced.

Stress Corrosion: This type of corrosion is usually seen on highly stressed parts like landing gear and engine crankshafts.

Crevice or Deposit Corrosion: This corrosion appears in areas of trapped moisture or pollutants.

Filiform Corrosion: This type of corrosion appears as fine, worm-like linesof corrosion under the paint. It will eventually lead to bubbling and flaking.

A product like PreKote allows our team to properly prepare the aircraft to paint, while also keeping the environment safe.

“The US Environmental Protection Agency (EPA) awarded PreKote for having environmentally preferable chemistry as a designation in the Design for the Environment (DfE) award. The EPA has also determined that PreKote is NOT one of the six core metal NOT trigger categorical industrial user (CIU) status. (3)
