    So glad to find the "good stuff" on Ebay. When high-cost, high-quality IGBT and SCR modules are at stake, it just makes good sense to use the best. Good price, fast shipping. A+++++

    I needed some of this for a repair, and I'm glad I found it on eBay. It's more than I need for now, but I'm sure that I'll have use for more if it in the future. (I just need to put it in a safe place) It arrived in good time and sealed in a plastic bag. The price is right

    Does the job well

    Dow has been known for quality for a long time, unlike so many other companys that no longer deserve to be called a quality product . So many things once proudly made in America now carry nothing but the name and are now made in other countrys so they can get richer. I have only used the compound once so far but its clear it does a very good job and worth a extra buck or two. In this case even the price was fare for a superior product. If I run out will buy the same product again.

  • Heat sink on amp.

    This produce work for me . Not sure what else could be used ? Just takes such a little bit like about 2 match heads worth. For my use a smaller container would have been fine. But this was the smallest amount I could fine. Nice to get my project done so I was glad to get this product. Dave

  • Good heat transfer

    I have used the Dow 340 for heat transfer from Mosfets to heat sink and have had very good results.

    Did the job and the size was just right. Didn't have to buy a lot for a small job.
