Product Description

Arctic Silver Thermal (not retail packaged) Adhesive features: Made with 99.8% pure micronized silver. 62% to 65% silver content by weight. Superior thermal conductivity. Greater than 7.5 W/m°K Temperature range: - 40C to >150C (Bond strength is weakened at very low temperatures due to crystallization.) Negligible electrical conductivity. Arctic Silver Thermal Adhesive was formulated to conduct heat, not electricity. 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-proximity electrical paths. 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

5.0 out of 5 stars great thermal adhesive... not just for CPU heatsinks anymore!, September 13, 2010

I ordered the Arctic Silver Thermal Epoxy 7-gram package through Platinum Micro in August 2010. My application for this epoxy had nothing to do with heatsinks or computer chips.

About a year ago I installed an "Ice Zapper" heating device on my DirecTV slimline satellite dish, which is mounted to a second-story soffit on my house. The Ice Zapper is a thermostatically controlled 120-watt heater with 2 rectangular heating pads that adhere directly to the back of the dish. It activates whenever the outside temperature (as measured by the thermostat built into the power cord) drops below 35 degrees F or so, and prevents snow and ice from accumulating on the dish. The Ice Zapper is not available through Amazon as of Sept. 2010, but can be found at SkyVision.

One of the Ice Zapper heating pads came unstuck last winter, and hung there for the rest of the winter while I figured out how to repair it. Any glue used to re-adhere the heating pad to the dish would need to be tolerant of high temperatures, and also should conduct heat efficiently from the heating pad to the dish. Tech support from SkyVision recommended that I use "Permatex" adhesive from my local auto parts store. The auto parts store had various Permatex adhesives, many of which were intended for high-temperature applications, but none were touted for their thermal conductivity. Then I discovered Arctic Silver Thermal Epoxy, and thought I would give it a shot.

The 7-gram Arctic Silver Thermal Epoxy kit consists of two 3.5-gram syringes. In my case I mixed the epoxy while standing near the top of a 24-foot extension ladder, outdoors at 80 degrees F. I strongly recommend wearing Nitrile gloves while you mix and apply the epoxy. I started a 5-minute countdown timer and then squeezed syringes A and B into a glob, and mixed them together with the included mini-spatula. For the first 4 minutes the mixture was on the runny side, and formed long runny strands when the spatula was lifted away from the mixing surface, like hot cheese on a pizza. It was easy enough to spread the Arctic Silver onto the back side of my satellite dish using the mini-spatula. The mixture covered a 1.5" x 9" area with ease, and thankfully my mixing surface was large enough to catch drips. Clamping the heating pad in place on the convex side of a satellite dish was not very practical, so I stood there pressing the item in place until the epoxy started to firm up. It took about 10 minutes for the glue to get thick enough to hold the heating pad in place. The nitrile gloves came in handy because the epoxy, when it was runny, squeezed out from the sides of the heating pad and got all over the dish, the heating pad, and my gloves.

The Ice Zapper is back in place again, makes good contact with the satellite dish, and I shall see this winter if the Arctic Silver had the desired result.

5.0 out of 5 stars best thermal epoxy, October 6, 2009

The most expensive but also the best thermal epoxy around. I use it in my DIY handheld lasers. If you don't need the best heat conduction, then a less expensive product will work.

5.0 out of 5 stars Cant Break it, January 8, 2011

Heat Sink mount broke of from the mother board, thought of giving it a shot using much heard Arctic silver thermal epoxy. Now the processor is bonded to the heat sink and does not get heated up...bond is strong that i can lift the whole CPU by the heat sink.

I would also recommend to use the arctic silver cleaner to remove the grease for better bond.
