DeltaCast™ 153 is a pourable casting resin having thermal expansion characteristics similar to aluminum and
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 isolation.
DeltaCast™ 153 is available in quarts and gallons. Order one bottle of hardener A4 or B-4 per one quart of
DeltaCast™ 153 separately. Shelf life: 2 years.
DeltaBond™ 154 is a medium viscosity, aluminum-filled resin with the best thermal conductivity of this series. It
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 brack-
