Note: In the event of conflict between the English and domestic language, the English language shall take precedence.

Purpose/Material Description.

The requirements listed in this specification must be met by all interior paint systems used in all GM vehicle interiors. Paint systems must follow the steps in Figure 1 to complete the paint approval process of a part.

Symbols.

Paint Types.

For a paint material approval, the paint system is required to be listed as approved in the GM Materials Approved Source List system. Paint systems approved to this specification shall be required to carry a type suffix to indicate the haptic feel that it has to the human skin. The suffix system shall be:

•Type C: Solid Color, Non-Haptic Paint

•Type D: Solid Color, Non-Haptic Paint, Primary Gloss C (PGC) Gloss Capable

•Type F: Satin Touch per GMHM012 Master

•Type G: Solid Color, Non-Haptic Paint, PGC Gloss Capable at Low Film Thickness

Applicability.

This specification covers requirements for an interior, waterborne or solventborne, one (1) or two (2) component paint system for use on driver airbag parts. All substrates must be tested per GMW16172 to confirm paintability.

Remarks.

Substrates can be pretreated by priming, fluorination, chlorination, plasma, flame, etc. A single pretreatment is required to achieve initial paint approval. The initial paint approval shall be linked to the specific pretreatment as listed on GM Materials Approved Source List. Additional pretreatments using the specific approved paint must be evaluated per Table 1, Column 1B and added to the comments section of the initial GM Materials Approved Source List approval. All new colors must be evaluated per Table 1, Column 2.

Haptic Approval for Type F.

Haptic feel must be approved by the GM Design Quality Paint Development Lead prior to evaluating the paint system performance. Paint types with an assigned GM haptic master shall have all paint system performance testing (Table 1, Column 1) reviewed by the region that originated the haptic master prior to GM Materials Approved Source List approval. After the system approval, color approvals are approved by any GM region.
