GMW17046

Description / Abstract: Material Description. This specification supercedes all prior regional specifications for interior paint performance for the General Motors Company and encompasses interior physical, environmental and chemical durability requirements for all underhood paints on plastic substrates. These paint systems can be metallic or non-metallic colors in both hard and soft haptic technologies. Paints covered by this specification can be applied to plastic substrates, flexible substrates, rigid substrates or integral skin foam systems.

The extended durability testing in this specification is required for corporate approval of all new underhood paints.

The requirements listed in this specification must be met by all paint systems used in GM vehicle engine compartments. This specification will be used to generically qualify red and blue colored paints for global paint technology approval. When a paint system is generically approved on a specific plastic, the paint system will then be approved to the appropriate interior paint specification and entered into the GM Materials Approved Source List (GMMASL). Once GMMASL approval is granted to a new paint system on a given class of plastics, specific color approval and Approval Paint on Plastic Systems (APOPS) testing (reference GMW14797 for interior trim components), will be required to complete the approval on that part. The approved paint system will then be entered into the APOPS database or documented through written approval from the responsible GM Materials Engineering department. The test requirements for APOPS testing will be found in GMW14797, Table A3 and Table A10.
