Description / Abstract: Material Description. This specification defines the adhesion requirements of exterior trim that is tape attached to painted or non-painted substrates. These requirements also include weatherstrips and seals that are tape attached, and flexible or metallic inserts tape attached, and used as a decorative component of a molding, applique, fascia, or sill plate assembly. The adhesive system is typically a double-coated foam, or elastomeric tape.

This specification covers the laboratory test requirements for Production Part Approval Process (PPAP) (Table A1, Appendix A), and Routine Quality Control (Table A2, Appendix A).

In addition to the tape/substrate combinations, approvals are also specific to the facility that laminates the tape to the part.

Typical Applications. This specification applies only to substrates, paint, adhesion promoters, and tape materials that have been qualified and approved to the appropriate GM specifications.

Double-coated foam or elastomeric tapes shall meet the requirements of GMW15201 for the appropriate tape type. Tape approvals to GMW15201 include adhesion testing to exterior topcoats

The process and requirements for obtaining GM Approval for Approved Adhesive Applications (AAA) has been removed from this specification. If it is required, GMW15625 will be added to the part drawing, or math data.
