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.
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. The suffix system shall be:
• Type C: Solid Color, Non-Haptic Paint
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 polyurethane. All substrates must be tested per GMW16172 to confirm paintability.
It is strongly recommended that paints approved to this specification are direct adhesion to polyurethanes. However, in some limited applications, polyurethane substrates can be pretreated by using a primer. All new colors must be evaluated per Table 1, Column 2.
