Epoxy Resin Removal

Written by steve smith | 13/05/2017

Epoxy resin is a compound used to secure objects together. For instance, it is used in computer motherboards to adhere chips to the main board. The material is very versatile in its uses and similar to glue in characteristics. Some differences exist, however. Epoxy can be reheated after it dries, and it is often used with fibreglass as a hardening agent to complete a form. Epoxy resin can be removed from any type of material.

Heat

One way to remove epoxy is to heat it above its hardening temperature. In most cases this is above 100 degrees C. Epoxy melts once it reaches this temperature and becomes fluid. Afterward, it becomes brittle and can be removed using a small knife or scraper. To heat the epoxy, use a heat gun or hot air gun. A torch or lighter is too hot for most projects and could damage the parts surrounding the epoxy. Always be conscientious when using a heat source because it may damage or melt important parts.

Chemicals

Some chemicals remove epoxy resins. These chemicals are not easy to find, however. They include toluene and xylene. Industrial epoxy removers come in chemical forms as well. These may be more effective for your particular epoxy type. If you know what kind of epoxy you are trying to remove, the first step should be locating the solvent that removes it. Each epoxy has a solvent that removes the compound after it is cured and dried. Some companies make both the epoxy and the solvent to remove it. Check hardware stores, model stores or auto shops to locate the proper solvent for your epoxy removal.

Considerations

Epoxy is a chemical compound, and when it is heated or melted, it releases gases and fumes. Inhaling these fumes over long periods of time may harm your body. Keep the room you work in ventilated well when you heat the epoxy or use a chemical to remove epoxy. Solvents also contain fumes that are harmful to humans. In addition, assess the objects you are working on prior to epoxy removal. Removing parts or chips will affect the operation of any object or machine.
