5. 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 5°C

(41°F) 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 20°C (68°F) per minute.

Second heat values given.

9. Coefficient of thermal expansion determined using DuPont (TMA) using a heating rate of 10°C (50°F) per minute. Second heat

values given.

10. Thermal conductivity determined using ASTM C177 and C-matic Instrument with 2 in. diameter samples.

11. Colour may vary from nearly white to yellow/amber. Adhesive performance is not affected by colour variation.
