There are a few things to consider if you’re in the market for epoxy resin. Well, when it was first discovered it came from coal tar, but nowadays, chemists extract it from petroleum (like so many other useful compounds). Epoxy resins can be homopolymerized or cross-linked into a three dimensional network using curatives. Whatever you use it for, there is one thing to remember: epoxy is temperature sensitive. It is a clear thick liquid and when it is mixed with polyamine hardener, it dried to be rock solid. The majority of resins are made up of two elements, namely the base resin and a catalyst (which is a hardener). Epoxy resin, or two-part epoxy, is a hard composite that is made when an epoxide and polyamine are combined. Epoxy is very moisture resistant, and certain formulations can even be applied underwater. 1. Resin. Epoxy resin is a hard substance created when two substances, a epoxide and a polyamine, are combined. Epoxy resins satisfy a variety of non-metallic composite designs in commercial and military aerospace applications including flooring panels, ducting, vertical and horizontal stabilizers, wings and more. Another common use of epoxy resin is in the field of protective coating called epoxy coating on the floor of gyms, factories and hospital floors, and which increases the resistance of concrete to environmental factors such as erosion and chemical attack. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. What is Epoxy Resin?
