Description
Parker Chomerics fully cured
dispensable GELs eliminate
timeconsuming hand assembly,
decreasing installation costs and
reducing customer manufacturing
and purchasing (logistical)
complexity. These products require
no mixing or curing, providing
superior design flexibility.
• Provides low thermal impedance
at thin and thick gaps, allowing
use of common heat spreaders
• Proven reliability in extreme
temperature cycling and shock &
vibration
• Deflects easily under very low
compressive forces, decreasing
stress on components thus
decreasing component failures.
Typical Applications
• Automotive Electronic Control
Units (ECU’s)
• Power Supplies &
Semiconductors
• Memory & Power Modules
• Microprocessors / Graphics
Processors
• Flat Panel Displays & Consumer
Electronics
Features/Benefits
• Easily dispensable
• Fully-cured / No pump out
• High bulk thermal conductivity
• Low thermal impedance
• Ultra low compression force
• High tack surface & reworkable
• Proven long-term reliability

ENGINEERING YOUR SUCCESS.
GEL 8010 & GEL 30 Thermally Conductive Dispensable Gels
Since GEL 8010 gel is conformable,
the gel can be stencil printed
onto the plates. The thickness of
the printed gel can be adjusted
depending on the component type
and size, but about 6mil thickness is
recommended.
Product Attributes
GEL 8010
• Thin bondline gel (approximately
2-10 mils)
• Low thermal impedance gel
• Stencil printable with no pump
out

• Proven long-term reliability
GEL 30
• Accommodates a variety of bond
line thicknesses for application
to multiple devices
• Gel 30 has been successfully
used to fill a variety of different
gap thickness. Please reference
the Gel 30 Reliability test report
for additional details and surface
recommendations.

GEL 8010 & GEL 30 Thermally Conductive Dispensable Gels
• INSTALLATION GUIDELINES
Thermal GELs are supplied in plastic
syringes and aluminum cartridges.
Apply pressure to the rear of the
cartridge, simply dispense the desired
amount onto components or cooling
plates. The gel is reworkable and
excess material can be easily wiped off
with a rag. Refer to Application Note for
more detailed information about using
these materials.
