epoxy, epoxy resin, epoxy glue - n

Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. The IUPAC name for an epoxide group is an oxirane.
An epoxy is a two-part adhesive that forms when you mix epoxy resin and hardener. The two substances are stored in different containers and are only mixed together when you’re ready for gluing – which you can do using a double syringe, for example. You should keep the mixing ratio 1:1, otherwise the resin will not cross link.
After you mix both components, the pot life begins. That is the period during which the parts to be bonded can still be moved and changed. The pot life can range from a few minutes to a couple of hours depending on the glue you use. After the pot life, the glue needs several hours to reach maximum strength.
