Arctic Silver Thermal Adhesive IS NOT intended to be used between a CPU and the CPU heatsink. On a CPU, only use. Arctic Silver Thermal Compound Please click on picture for larger image. Silver Adhesive Features: Made with 99.8% pure micronized silver. 62% to 65% silver content by weight. Superior thermal conductivity. Greater than 7.5 W/mK Temperature range: - 40C to >150C (Bond strength is weakened at temperatures below 0C due to crystallization.) Negligible electrical conductivity: Arctic Silver Thermal Adhesive was formulated to conduct heat, not electricity. NOTE: Even though Arctic Silver Thermal Adhesive is specifically engineered for high electrical resistance, it should be keep away from electrical traces, pins, and leads. The cured adhesive is slightly capacitive and could potentially cause problems if it bridged two close-proximityelectrical paths. Compliancy: RoHS Compliant. Arctic Silver Thermal Adhesive is sold in: A set of Arctic Silver Thermal Adhesive consists of two tubes containing a total of 7 grams of adhesive (3.5 grams of Part A and 3.5 grams of Part B) and a plastic reusable mixing wand.
