Rev. E (2/21) Page 1 of 2 CircuitWorks Silicone Free Heat Sink Grease Product# CW7270 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 -99.4°F(-73°C) to 392°F (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 Typical Product Data and Physical Properties Color: Specific Gravity: @ 25°C (77°F) Usable Temperature Range: Dielectric Strength: v/mil Dielectric Constant: @ 100 Hz Dissipative Factor: @ 100 Hz Volume Resistivity: ohm-cm Arc Resistance: seconds Thermal Conductivity: Cal-cm/sec-cm2 -°C BTU-in/hr-ft2 -°F W/m°K Shelflife White 2.4 RoHS Compliant Yes -99.4°F (-73°C) to 392°F (200°C) 500 4.4 0.002 1 x 1012 120 1.7 x 10-3 4.92 0.71 5 years 1-770-424-4888  www.chemtronics.com Rev. E (2/21) Page 2 of 2 CircuitWorks Silicone Free Heat Sink Grease Product# CW7270 Availability CW7270 Compatibility CircuitWorks Silicone Free Heat Sink Grease is generally compatible with most materials used in printed circuit board fabrication. Material Ceramic Clean Metals Glass Silicone Resins Painted Surfaces Plastic Surfaces Vulcanized Silicone Rubber Environmental Impact Data ODP HCFC VOC HFC Compatibility Good Good Good Good Good Good Good Usage Instructions None None None None 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. For industrial use only. Read SDS carefully prior to use. 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. 8 gm / 0.28 oz Syringe Technical and Application Assistance Chemtronics provides a technical hotline to answer your technical and application related questions.
