Material Description.

This specification covers the requirements for the flame treatment surface preparation of plastic parts. A flame treatment is required to enhance adhesion of the coatings to non-polar plastic surfaces. Suitable flame treatment may eliminate a priming step in the coating process.

Surface preparation is part of a total painted product system and must meet requirements set forth in this specification and those shown in engineering drawings. This specification shall be used in conjunction with the Approved Paint on Parts System (APOPS), a section of the GM Materials Approved Source List (GMMASL), which lists approved substrate, cleaning preparation, priming and topcoat combinations.
