The reactivity of epoxyethane Ring strain The reason that epoxyethane is so reactive is that bonding pairs in the ring of atoms in the molecule are forced very close together. The bond angles are about 60Â° rather than about 109.5Â° when carbon atoms normally form single bonds.hen epoxyethane reacts a carbon-oxygen bond is always broken and the ring opens up. Uses of epoxyethane Manufacture of ethane-1,2-diol (ethylene glycol) Acid catalysed hydrolysis of epoxyethane Epoxyethane reacts with water in the presence of an acid catalyst (very dilute sulphuric acid) at a temperature of about 60Â°C.
Epoxy glue is an extremely versatile, general purpose adhesive that has been around for a very long time. It can be used to bond paper, metal, plastic, polyurethane foam, glass, fiberglass and wood with smooth or porous surfaces. It can also be used for filling gaps. Epoxies come in a two part system that requires the epoxy and the hardener to be mixed before application. Most epoxies dry in 5 to 20 minutes and completely cure in about 12 hours. When dry, the epoxy is fuel proof, water proof and will not shrink. Epoxies do not work well on flexible surfaces.
