Alternately, resin casting may be accomplished with a resin plus a nearly equal amount of a "hardener" liquid (as in many epoxy resin or polyester resin systems), which functionally contains a second polymer, for use in forming a final product plastic which is a copolymer. Copolymers contain two different alternating chemical entities in the ...
The method of casting compared to steel allows easier inclusion of inserts etc. and thus reduced machining of the finished casting and reduced assembly time by incorporating multiple components into one casting. [12] Polymer cast resins use very little energy to produce, and the casting process is done at room temperature. [13]

The first batches of Araldite epoxy resins, for which the brand is best known, were made in Duxford, England in 1950. [1] Araldite adhesive sets by the interaction of an epoxy resin with a hardener. Mixing an epoxy resin and hardener together starts a chemical reaction that produces heat – an exothermic reaction. [2]
Thermosetting plastics or silicone rubber gels are often used, though epoxy resins are also very common. When epoxy resins are used, low chloride grades are usually specified. [1] Many sites recommend using a potting product to protect sensitive electronic components from impact, vibration, and loose wires. [2]
