Description / Abstract:
Material Description. Heat curable structural
bonding tape with integrated pressure sensitive adhesive. The tape
is typically protected with a suitable release liner.
• Type I tape is intended for medium/high bake plants.
• Type II tape is intended for low bake plants. Contact
engineering for specific plant bake schedules.
Symbols. Not applicable.
Applicability. This specification covers the
durability and adhesion performance requirements for curing
structural bonding tapes for exterior trim applications. The
adhesive material is used primarily for the attachment of roof
ditch molding clips to roof ditches. Other applications may include
the attachment of appliques or other trim parts.
Remarks. This specification covers the
laboratory test requirements for GM Approved Adhesive Applications
(AAA), Production Part Approval Process (PPAP), processing
conditions and routine quality control. In regions other than
General Motors North America (GMNA), the AAA process is
optional.
In addition to the substrate/adhesive/substrate combinations,
approvals are also specific to the facility that does the adhesive
bonding.
