Adhesive, One-Part, Structural, Fracture Toughened, Full Temperature Spectrum
|Publication Date:||1 December 2016|
Material Description. This specification describes a pumpable, one component structural adhesive that is cured in the heat of the paint bake ovens. This adhesive is specifically formulated to provide increased energy absorption through a temperature range of -40 °C to +80 °C.
Symbols. Not applicable.
Applicability. 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 production phosphate, Electro Deposition Paint Coating (E-coat), and topcoat systems.
Structural bonds resulting from the use of this material shall provide an adhesive strength to the substrate (oily Cold Rolled Steel (CRS), galvanized or aluminum), that is greater than the materials cohesive strength 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.
