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.

Note: APOPS = Approved Paint on Parts.

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 classification and the haptic feel that it has to the human skin. The suffix system shall be:

• Type C: Non-Haptic Paint, PGF Gloss Capable

• Type C(LE): Laser Etch

• Type C(BC): Basecoat/Clearcoat

• Type D: Non-Haptic Paint, PGC Gloss Capable

• Type F: Satin Touch per GMHM012 Master, PGC Gloss Capable

• Type M: Metallic

• Type M(BC): Metallic Basecoat/Clearcoat

• Type M(LE): Metallic Laser Etch

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.

Applicability. This specification covers requirements for an interior, waterborne or solventborne, one (1) or two (2) component paint system for use on parts made of paintable styrenics including acrylonitrile butadiene styrene (ABS), polycarbonate (PC), and acrylonitrile butadiene styrene plus polycarbonate (ABS+PC) blends. All substrates must be tested per GMW16172 to confirm paintability.

Remarks. It is strongly recommended that paints approved to this specification are direct adhesion to styrenics. However, in some applications such as Type F, styrenic substrates can be pretreated by using a primer. All new colors must be evaluated per Table 1, Column 2.
