III. Bond Building/
Rework (continued)
Anodized Aluminum Substrates
As one can see from the data below, anodized aluminum substrates show very rapid
building of the peel strength. The initial bond is nearly 80% of the final levels and the
effect of elevated temperatures is diminished. Both the final peel strengths obtained,
as well as the rate of bond building appear to be the same for either room temperature
dwells or 70¡C dwell.
Effect on Thermal Resistance
In a spot check over a 24 hour period, the thermal properties of the adhesive did not
appear to change beyond the 20% - 25% margin of error of our experiments.
However it is believed that wetting of the surfaces by the adhesive and strong
adhesion levels contribute to yield optimum thermal properties.
Rework
The procedure for reworking bonds made with the adhesive.
A) Mechanically separate the parts, using torque for rigid parts and peel for flexible
B) Remove the adhesive by rubbing if off with a tool. Use solvent only as a last
C) Clean the surfaces using isopropyl alcohol. If gross contamination exists, use
D) Apply fresh adhesive and repeat the bonding procedure.
Note: Carefully read and follow the manufacturerÕs precautions and directions for use

ones. The amount of force required will depend on the bond area and the extent
to which the bond has built, as described above. Heating the substrates and
adhesive (with a hot air gun or other means) to 70¡C - 100¡C will soften the
adhesive bond and allow the amount of force to be reduced.
