What is Epoxy?

Lucky for all of us, and contrary to some beliefs, polyamine is legal outside of Utah, which allows all of us to enjoy the benefits of epoxy. So, what is epoxy? The important thing to know is that epoxies are two-part polymers. That is, by definition, epoxy must be composed of two parts that are mixed together. It can be a glue, paint, putty, etc. In each case, a true epoxy will have both a "resin" and a "hardener," and that is the first and most important thing to note.
Now, for those of you interested in the historical side of things, epoxy was first formulated in the 1920s and 30s by a Swiss chemist, Dr. Pierre Castan, and an American, Dr. S.O. Greenlee. Naturally, their discoveries went on to be licensed by major corporations, and little else was heard from these fine scientists.
The many uses, of course, are what we associate with epoxy today. From coating a concrete garage floor, to refinishing the bright work on a sailboat, epoxy has become a near and dear tool for many craftsman. First and foremost, epoxy is thought of as an adhesive, and for good reason. Once epoxy cures, there is simply nothing better for the job. A common demonstration that comes to mind is one in which two boards are epoxied together and given time to cure. Afterwards, the boards are attached to large machines attempting to rip them apart and thereby test the strength of the epoxy. Of course, what ends up being revealed are weaknesses in the wood itself, as it splinters and tears, leaving the epoxy bond intact.
But beyond it's adhesive properties, it has been well established that epoxy also has an incredible ability to waterproof. It would be a not inconsiderable challenge to find any wooden boat still on the water that does not have some epoxy on board. As you might imagine, epoxy makes for one of the best wood glues, and is the ideal solution for boat builders looking to build or repair a wooden boat. Unbeatable 'stickiness' plus waterproofing is just an irresistible combination. It should be mentioned that UV exposure can, over time, weaken epoxy, but that can be counteracted, and we will save that for a later post.
Answer the question of "what is epoxy" in recent years has become more difficult. Today, people are constantly finding new uses for epoxy. From painting their decks and sheds, to painting large pieces of art, epoxy is finding it's way into new and diverse venues all the time. Even toothbrushes are getting in on the act - In fact, each Sonicare toothbrush has epoxy surrounding the electronic components in the handle to protect against damage in the event of a fall. Or maybe that's just so we can't fix them when they do break.
