Formula changed!
We use this epoxy weekly and have been buying it for many years. However, the last batch we purchased was a gel formula instead of the liquid we have become accustom to. Do no like it very much as it is difficult to fill a syringe and use it in the field.

I have been using OB-101 in the small packs for several years now to bond the printed circuit board to the frame/case, which as also the heat sink, on automotive Engine Control Modules manufactured with surface mount components. It withstands thermal expansion and contraction, and vibration, while also being a good thermal conductor and yet a good electrical insulator.
Shelf life is substantially longer that what is marked on the packets.

Good Product and great service.
We have been using this epoxy for many years and have not experienced any issues with the exception of the more recent texture difference with part A. It used to be smooth and now it is more chunky and dry, making it hard to measure. By warming it up beyond room temperature, we are able to soften it making it easier to portion. This extra step takes away 1 star. The service the company provided is excellent with order follow through and general customer service.

Thermal Epoxy Works Great
I like the variety of potting and full cure times at room temp and with heat. This tends to hold on to my thermocouples well.

Way too long to ship.
The product works as expected but a 3 week lead time is ridiculous.
