Robert--Very informational.  Excellent post.   Am I correct in saying the Tg temperature is somewhat like the "triple point" for other materials?   Would this be a decent analogy?  Also, I'm assuming all adhesives have a Tg temperature.  In looking at the adhesives I use and see used on a daily basis, we are very concerned that we apply adhesive to a part and adhere that part to a substrate before that adhesives "skins over".    The only way for us to insure compliance with our customers "pull test" requirements.

Thanks for a very educational piece of material. I learned quite a bit, and now have a much btter understanding of what the temperature ratings of epoxy materials are all about.

In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
