Viscosity determined using 3M test method C-1d. Procedure involves Brookfield RVF, 6 spindle, 20 rpm and 80F (27F). (100 Clear) and 6 spindle, 4 rpm and 80F (27F) (100 NS). Measurement taken after 1 minute. 2. Worklife determined using 3M test method C-548. Procedure involves periodically measuring a 10 gram mixed mass for spreading and wetting properties. This time approximates the usable worklife in an EPX applicator nozzle. 3. Gel time determined using 3M test method C-554. Procedure involves periodically checking a 10 gram mixed mass for flowing properties. 4. Color may vary from nearly white to yellow/amber. Adhesive performance is not affected by color variation. 3M Scotch-Weld Epoxy Adhesives DP-100 Clear DP-100 NS Translucent Note: The following technical information and data should be considered representative Typical Cured or typical only and should not be used for specification purposes.

Handling strength determined per 3M test method C-3179. Time to handling strength is the time required to achieve 50 psi OLS strength to aluminum. 6. The cure time is defined as the time required for the adhesive to achieve a minimum of 80% of its ultimate OLS on aluminum. 7. Weight loss by Thermal Gravimetric Analysis reported as that temperature at which 5% weight loss occurs by TGA in air at 5C (41F) rise per minute per ASTM 1131-86 Test Procedures. 8. Glass transition temperature (Tg) determined using Perkin Elmer (DSC) Analyzer with a heating rate of 20C (68F) per minute. Second heat values given. 9. Coefficient of thermal expansion determined using DuPont (TMA) using a heating rate of 10C (50F) per minute. Second heat values given. 10. Thermal conductivity determined using ASTM C177 and C-matic Instrument with 2 in. diameter samples. 11. Color may vary from nearly white to yellow/amber. Adhesive performance is not affected by color variation. - 2 -
