Epoxy is a two-part adhesive like all types of epoxy resin. Part A is the base material and part B is the hardener. Equal proportions of the two parts are mixed so that the chemical reaction takes place and hardening and bonding takes place. We do this mixing process only before working with it directly, and it is either in the form of a syringe with which the two components are mixed or Each component in a separate tube. After mixing both tubes, the reaction process begins. Here, the epoxy must be applied to the parts to be glued. We must try to fix the parts for some time until the bonding is complete. The full bonding time varies according to the type. There are types that need a few minutes, and there are types that need hours to reach maximum strength.
