Form

This specification establishes requirements for three types of corrosion preventative coatings for protection of aircraft integral fuel tanks.

Application

The coating materials covered by this specification are typically applied to the interior of aircraft integral fuel tanks to protect against corrosion from fuel contaminants, but usage is not limited to such applications. They are suitable for use in a service temperature range from -65 to +250 °F (-54 to +121 °C).

Classification

The coating materials covered by this specification shall be classified as follows:

Type 1 - A two-component polyurethane coating with less than 420 g/l Volatile Organic Compound (V.O.C.) content

Type 2 - A two-component polyurethane coating with less than 720 g/l V.O.C. content

Type 3 - A chrome-free coating with less than 420 g/l V.O.C. content

Grade 1 - Standard

Grade 2 - Diethylene Glycol Monomethyl Ether (DiEGME) resistant

Note: If no type is specified, Type 2 is the default classification. If no grade is specified, Grade 1 is the default classification.

Safety - Hazardous Materials

While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
