copper allowing assemblies to operate over a very wide temperature range. Ideal for encapsulating components
and assemblies, this series' major advantages and uses include potted systems (virtually indestructible), protecting
components and systems from moisture and contaminants, securing proprietary circuitry, mechanical support of
devices, removal of heat from hot components and the assembly equalizing temperatures, and high voltage isola-
tion.

is, however, neither a good electrical insulator nor conductor. Its principal application is that of a good thermal
mechanical adhesive for applications such as bonding fins to base plates or structural mounting blocks or brackets
to heat sinks. Order one bottle of hardener A4 or B4 per one quart of
years.
