This specification covers the requirements for a low bake 80 °C (180 °F) solventborne adhesion promoter for Thermoplastic Polyolefin (TPO). The adhesion promoter may be conductive or nonconductive depending on the needs of the user.

Note: Nothing in this standard supercedes applicable laws and regulations.

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

Purpose/Material Description.

This adhesion promoter is part of a total product system and must meet requirements set forth in the specifications for other materials with which it is used. This specification shall be used in conjunction with the GMW14797, Approved Paint on Plastics Systems (APOPS) a section of the GM Approved Materials Source List (GMMASL), which lists approved substrate, cleaning, priming, and topcoat combinations.

Specified herein the material requirements per the Manufacturing Engineering (ME) Vehicle Systems Paint Materials and Facility Group. These specifications are used to verify the materials have been processed to produce a finished product of quality consistent with that proven in initial qualification testing.
