Characteristic Description
THERMAL COMPOUNDS, ADHESIVES AND INTERFACE MATERIALS
The 120 Series Silicone Oil-Based Thermal Joint Compound fills the minute air gap between mating surfaces with
a grease-like material containing zinc oxide in a silicone oil carrier. It possesses an excellent thermal resistance of
only 0.05°C/W for a 0.001 in. film with an area of one square inch. There is no measurable increase in case tem-
perature of a mounted semiconductor on a heat sink after the 6-month stabilization period (Time versus Thermal
Resistivity graph below).

HIGH PERFORMANCE THERMAL COMPOUND
122 Series Thermal Joint Compound is a stable, silicone based, thixotropic paste developed to provide premium
performance at an affordable price. It is formulated to significantly reduce contact thermal resistance where
power densities are concentrated in devices such as flip chip, reduced die size, and ‘overclock’ microprocessors.
When applied as a thin film between a Wakefield heat sink and device it possesses superior thermal conductivity
compared to traditional ‘grease’. It is compatible with automated or manual dispensing methods and is fully RoHS
compliant.

NOTES:
* Since the hardener/resin reaction is exothermic, it is important that batch size be matched to hardener speed. Working times given are for approximate batch sizes: A—200 gms,
B—200 gms. Larger batch sizes will greatly reduce working time.
** For optimum electrical properties, dry parts for 15 minutes at 150°F (65°C) or 30 minutes at 75°F (24°C) to slowly evaporate the thinner and then final cure for 4 hours at 275°F
(135°C).
† After initial cure, material may be handled, removed from fixture, etc., but has not yet achieved full properties and should be room temperature aged or post-cured as shown to
achieve full physical and electrical properties.
‡ After initial cure, material may be brought to full physical and electrical properties during post-cure or may be room temperature aged for charted length of time to achieve same
full properties.

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 isola-
tion. DeltaCast™ 153 is available in quarts and gallons. Order one bottle of hardener A4 or B4 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 brackets
to heat sinks. Order one bottle of hardener A4 or B4 per one quart of DeltaBond™ 154 separately. Shelf life: 2
years.

DeItaBond™ 155 is an epoxy adhesive formulated for use within the semiconductor industry. An easy to mix spread
thixotropic paste, it offers high heat transfer, low shrinkage, and a coefficient of thermal expansion comparable to that of
copper and aluminum. This adhesive is principally used to form thermally conductive joints in fabricated heat sinks and
between heat sinks and power devices. When used to bond semiconductors to heat sinks, it also serves as an electrical
insulator. Its strong bond to a wide variety of substrates resists severe temperature cycling. DeItaBond™ 155 is only
available in kit size. Simply squeeze out equal lengths and mix to uniform color. Shelf life: 1 year.
DeltaBond™ 156 Thermally Conductive Adhesive is a modified acrylic adhesive designed for permanent mounting on
components where heat must be effectively transmitted. Recommended for electromechanical assemblies to bond com-
ponents and dissipate heat, it replaces mechanical fasteners and compressible pads, silicone grease, and epoxies; elimi-
nates air entrapment, and other variables related to epoxy mixing. This soft paste requires no mixing and flows easily to
allow thin bond lines. Primer activated, cure begins upon assembly. DeltaBond™ Activator fixtures at room temperature
in less than 5 minutes. Full strength is developed in 4 to 12 hours and fillets become dry to the touch in 24 hours. It is
not recommended to use this durable adhesive without the use of DeltaBond™ Activator. DeltaBond™ 156 is available in
kit size; order 156-K (25 ml Syringe and Activator Kit). Shelf life: 1 year.
