USG271 is a thermally conductive filling and potting compound. It is a high purity, readily flow, addition-curing, two-component silicone that cures at room temperature or elevated temperature to a solid rubber with flexibility and thermal conductivity. The cured material has low thermal stress for thermal cycles. It provides superior resistance to moisture and media corrosions. USG271 is dispensable.
Special Features and Benefits
• High thermal conductivity
• High purity for electrical insulation
• Fast cure profile and ambient curable
• Properties stable from –55 to 180 °C
• Low modulus for stress compliance
• Low bleeding, low volatile
• Automotive electronics
• Semiconductor and Telecommunications
• Between high heat power device and heat sink
• Thermally conductive vibration dampening
• Couple thermal stress while dissipating heat
USG271 has a shelf life of at least 12 months when stored between 5°C and 30°C in the originally sealed container. After cure it forms a low modulus rubbery material that is not for structure bonding purpose. For bonding thermally conductive adhesive, please select the USGlue’ “ThermoBond” products.

Important! USG271 is platinum cure system. Please keep applied surface clean and avoid using this material on any surface that contains sulfur, amine, phosphorous, organo-metals, acid, etc. because these contaminants could inhibit the cure of the material.
Only components A and B with the same lot number may be processed together! For the package in a container (not in a cartridge), to ensure homogeneity of the material, the components must be stirred thoroughly before they are removed or processed in order to uniformly disperse any fillers that might have settled during storage.
We recommend running preliminary tests to optimize conditions for the particular application. Comprehensive processing instructions can be obtained by contacting directly to USGlue.com.
USG271 has a shelf life of at least 12 months when stored between 5°C and 30 °C in the originally sealed container. The 'Best use before end' date of each batch appears on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
Addition curing USG271 silicone gel contains neither toxic nor corrosive substances that might require special handling precautions. General hygiene regulations should be observed. Comprehensive instructions are given in the corresponding Material Safety Data Sheets. They are available on request from USGlue.com.
