Material Description. This specification describes a pumpable, one-component, fracture toughened adhesive suitable for automotive applications, such as, vehicle body panels and reinforcements. This material shall be used in the Body Shop or Fabrication Plant, on "oily metal", and cure in the heat of the Paint Bake Ovens.

Symbols. Not applicable.

Applicability. "Weld-bonding" of typical automotive flanges, with resistance weld spacing to be determined by the requirements of the application.

Remarks.

Structural bonds resulting from the use of this material shall provide an adhesive strength to the substrate (oily Cold Rolled Steel (CRS), galvanized steel or aluminum), that is greater than the cohesive strength of the material when tested in shear, tension and/or peel.

Adhesive materials approved to this specification shall be capable of maintaining bond integrity of test samples and assemblies that are fatigue tested to the prescribed frequency, load, total cycles and environment listed in the associated performance specification.

This material shall be compatible with current application equipment and it is recommended that the dispensing equipment be capable of "conditioning" the material to a dispense temperature of approximately 38 °C. This material shall also be compatible with GM production wash, pretreatment, and paint systems. This material shall not be adversely affected by maximum production paint bake temperatures.
