CircuitWorks Boron Nitride Heat Sink Grease
PRODUCT DESCRIPTION
CircuitWorks
Boron Nitride Heat Sink
Grease facilitates heat transfer away from
electrical/electronic components and into
heat
sinks.
The
material
exhibits
exceptionally high thermal conductivity with
outstanding
dielectric
properties
(nonconductive).
CircuitWorks
Boron
Nitride Heat Sink Grease shows no creep or
migration over a wide temperature range. The
grease contains an efficient heat conducting
filler that enhances the effectiveness of heat
sinks on electrical/electronic equipment.
Exceeds MIL-C-47113 for thermal
conductivity
Noncorrosive
High dielectric strength
Stable from -73°C to 200°C
Nonflammable
TYPICAL APPLICATIONS
CircuitWorks
Boron Nitride Heat Sink
Grease may be used for electronics
applications including:
Effective Thermal Coupler for any
Heat Sink Device
Nonflammable Protective Coating
High Voltage Corona Protection
Excellent for Improving Readings on
Contact Type Thermocouples
Ideal for Silicone Sensitive
Environments

Ozone depletion potential (ODP) is determined in accordance with the
Montreal 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.
USAGE INSTRUCTIONS
For industrial use only.
Read MSDS carefully prior to use.
Application:
Apply CircuitWorks
Boron Nitride 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.
