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 Haptics. For a paint material approval, the paint system
is required to be listed as approved in the GM Materials File
(MATSPC) 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: Hard Touch
Type D: Semi-soft Touch
Type F: Satin Touch per GMHM012 Master
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 1A)
reviewed by the region that originated the haptic master prior to
MATSPC 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 driver air bag 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 MATSPC. Additional pretreatments using the specific
approved paint must be evaluated per Table 1, Column 1B and added
to the comments section of the initial MATSPC approval. All new
colors must be evaluated per Table 1, Column 2.
