Description / Abstract:
This specification covers plastic powder coatings that are fused on application to properly prepared metal substrates to form a continuous, durable coating for purposes such as wear resistance or squeak prevention. The powders may be applied by electrostatic spray, fluidized bed, or a variation thereof.
Material Description. Six (6) types are covered by this specification, as follows:
• Type I: A thick epoxy coating for usages such as seat belt anchor plates, to provide corrosion resistance and prevent metal edges from cutting the webbing.
• Type II: A thinner epoxy coating used on various seat parts and other parts where prevention of metal-tometal contact is required and where some degree of wear resistance is necessary.
• Type III: A thick nylon 11 or nylon 12 coating used on parts which are susceptible to high wear, to prevent squeaks, or to provide a thermal barrier.
•Type IV: A thinner nylon 11 or nylon 12 coating.
• Type V: A polyester coating for usages such as seat tracks, where some degree of wear resistance is necessary.
• Type VI: An alloy of Acid Modified Polyolefins used on parts which are susceptible to wear, to prevent squeaks.
Note: Some nylons must use a primer to meet the performance requirements of this specification.
Symbols. Suffix codes are to be added to the drawing notes to indicate location on the vehicle and if the coating is exposed to sunlight:
• Exterior (EX) = Exterior applications - includes underhood and underbody.
• Interior (IN) = Interior applications.
• Ultraviolet (UV) = Applications exposed to sunlight whether interior or exterior.
Applicability. These coatings are typically used for corrosion resistance, seat belt anchor plates, prevention of metal-to-metal contact such as on seat parts, protection from wear, etc.
Note: Epoxies should not be used in applications where they are exposed to sunlight.
Remarks. Appropriate suffix codes of materials approved under this specification shall be part of the approved sources documentation per Section 6.
