This specification covers the requirements for both grey and black thermosetting powder paints.

Type One (1) (grey) and Type Two (2) (black) coatings are intended to act as a corrosion resistant primer, where exposure to Ultraviolet (UV) light would require the use of a weatherable topcoat.

Type Three (3) (grey) and Type Four (4) (black) coatings are intended to be used as a single coating that would provide a smooth, hard, corrosion and moderately UV resistant finish.

These coatings are intended to be applied over metallic substrates that have been previously coated with zinc phosphate (9984123), iron phosphate or other GM approved pretreatments.

Material Description. Thermosetting powder paints for underhood and chassis components.

Symbols. Not applicable.

Applicability. Type One (1) and Type Two (2) coatings are intended to provide corrosion protection to underhood and chassis components that are generally not exposed to UV light such as: tie rod ends, intermediate drive shafts, steering linkages, brackets, pulleys, etc. Type Three (3) and Type Four (4) coatings are intended to provide UV protection to underhood and chassis components that have limited exposure to UV light such as: trailer hitches, exposed fuel tanks, entry steps, exposed battery boxes, tow hooks, etc.

Remarks. None.
