Material Description.This specification defines the adhesion requirements of exterior trim that is attached to painted or non-painted substrates. These requirements also include weatherstrips and seals that are tape attached. The adhesive system is typically a double-coated foam, or elastomeric tape.

This specification covers the laboratory test requirements for GM Approved Adhesive Applications (AAA), Production Part Approval Process (PPAP) approval, processing conditions, and routine quality control.

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

Applicability. 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.

The requirements of this standard shall be met over all production intent paint systems, or mold-incolor (MIC) plastics.

The requirements of this standard shall be met over all production intent paint systems, or mold-incolor plastics. In addition, any bright strip, or other styling feature, tape attached to the "A" surface of a molding, or cladding shall meet all requirements of this standard.
