High Bake Adhesion Promoter - Solventborne for TPO
|Publication Date:||1 May 2019|
This specification covers the requirements for a high bake 121 °C (250 °F) waterborne adhesion promoter for Thermoplastic Polyolefin (TPO). The adhesion promoter may be conductive or nonconductive depending on the needs of the user.
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 GM Materials Approved Source List which lists approved substrate, cleaning, priming, and topcoat combinations.
Specified herein are material requirements per the Manufacturing Engineering Vehicle Systems Paint Materials 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.
Symbols. Not applicable.
Applicability. Adhesion promoters covered under this standard are typically applied to a GM approved TPO substrate. Adhesion promoters are used under an approved coating system.
