CircuitWorks® Silicone Free Heat Sink Grease
PRODUCT DESCRIPTION
CircuitWorks® Silicone Free Heat Sink
Grease facilitates heat transfer away from
electrical/electronic components and into
heat sinks. This silicone-free compound
shows no creep or migration over a wide
temperature range. Thickened with a
proprietary thermally conductive zinc oxide
ceramic, the CircuitWorks® Silicone Free
Heat Sink Grease creates an effective heat
sink interface in electrical/electronic
equipment.
ƒ Exceeds MIL-C-47113 for thermal
conductivity
ƒ Noncorrosive
ƒ High dielectric strength
ƒ Low migration
ƒ Stable from -15°C to 200°C
ƒ Nonflammable
TYPICAL APPLICATIONS
CircuitWorks® Silicone Free Heat Sink
Grease may be used for electronics
applications including:
ƒ Effective Thermal Coupler for any
Heat Sink Device
ƒ Nonflammable Protective Coating
ƒ High Voltage Corona Protection
ƒ Excellent for Improving Readings on
Contact Type Thermocouples
ƒ Ideal
for
Silicone
Sensitive
Environments

USAGE INSTRUCTIONS
For industrial use only.
Read MSDS carefully prior to use.
Application:
Apply CircuitWorks® Silicone Free Heat
Sink Grease directly to surface or use the
application tip. Remove cap from syringe
and gently depress the plunger. Spread the
material in a thin layer on all mounting and
threaded surfaces of the device and the
chassis.
Clean-Up: Wipe away excess material
using a Chemtronics® ControlWipes™ and
thoroughly clean the surface using
Chemtronics® Electro-Wash® PX.

Protocol
and
U.S.
Clean
Air
Act
of
1990.
Hydrochlorofluorocarbons (HCFCs) are regulated under the Montreal
Protocol as Class II ozone depleting substances. Volatile Organic Compound
(VOC) information is calculated on a weight basis using the VOC definition
of California Air Resources Board (CARB) Consumer Product Regulations,
South Coast Air Quality Management District (SCAQMD) Rule 102 and the
Federal definition published in 40 CFR 51.100(s). Hydrofluorocarbons
(HFCs) are not currently regulated.
