scope:

This specification covers the requirements for a low bake 80 °C (180 °F) solventborne or waterborne stand-alone adhesion promoter for thermoplastic olefins (TPO). The adhesion promoter may be conductive or non-conductive, depending on the needs of the user.

Material Description. This adhesion promoter is part of a total painted product system and must provide a smooth, adhesion-promoting coating direct to substrate, specifically TPO. This specification shall be used in conjunction with the Approved Paint on Plastics Systems (APOPS), a section of the GM Materials Approved Source List, which lists approved substrate, cleaning, priming, and topcoat combinations. APOPS test requirements are defined in GMW14797.

Symbols. Not applicable.

Applicability. This primer/adhesion promoter can be used on TPO only and is generally used on service part applications.

Remarks. Not applicable.
