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.

Exceeds MIL-C-47113 for thermal

conductivity

Noncorrosive

High dielectric strength

Low migration

Stable from -15

°C to 200°C

Nonflammable

TYPICAL APPLICATIONS

CircuitWorks

®

Silicone Free 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
