- the content of alumina is preferably limited to a level including 40 to 70% by weight relative to the total solids weight in the adhesive composition. If the content of alumina is less than 40% by weight, the thermal conductivity may drop sharply.

If the softening point of the phenol novolak resin is less than 80 ° C., the crosslinking density is remarkably low and thus the desired lead heat resistance cannot be secured. On the other hand, when using a phenol novolak resin of more than 130 °C can obtain a high cross-link density, not only can not obtain significantly more physical properties than the desired lead heat resistance, there is a disadvantage that the adhesive strength is significantly reduced.

- the aromatic amine is excellent in adhesiveness and heat resistance of the cured product after curing reaction with epoxy.
