Understanding the A to Z of Epoxy Resin
The term epoxy has been widely adapted for many uses beyond fiber reinforced polymer composites. Today, epoxy adhesives are sold in local hardware stores, and epoxy resin is used as the binder in countertops or coatings for floors. The myriad of uses for epoxy continues to expand, and variants of epoxies are constantly being developed to fit the industries and products they are used in. Here are some things that epoxy resin is used in:
• General purpose adhesives
• As the binder in cement and mortars
• Rigid foams
• Non-skid coatings
• Solidifying sandy surfaces in oil drilling
• Industrial coatings
• Potting and encapsulating media
• Fiber reinforced plastics
Epoxy is thermosetting. That means that it cures depending on the surrounding temperature. Once epoxy is cured, it cannot be uncured. Epoxy is an epoxied, which simply means that it’s more reactive to other chemicals. A polyepoxide such as epoxy is made up of unreacted epoxide. This basically means that pure epoxy is extremely susceptible to reactions with other chemicals. The other chemical in the case of epoxy is a hardening or curing agent which works to cure it into a very strong adhesive.
Epoxies are created through reacting an epoxy resin and a hardener or simply by reacting the resins themselves. The vast majority of epoxy resins are themselves an industrial product which are derived from petroleum and are also the result of an epoxide reactive process. All depending on the type of reaction that was used to produce them, cured epoxy resins can either be like honey, or something much more viscous. Their actual molecular weight will determine the uses that you can get out of them.
Epoxy resins are very stable at room temperature and only cure when reacting with some kind of curing agent. Epoxies are the most common coating that’s used in the field of wastewater. These are based on reactions which are made with still further reactions. We will now take a look at the different types of epoxy that are out there.
Uses of Epoxy Resin:
• One of the most common uses of epoxy resin is for adhesive purposes. That’s because the strong-properties of the epoxy allow for structural and engineering adhesives. Commonly, epoxy resin is used in the construction of vehicles, snowboards, aircrafts and bicycles.
• Placing an important part in the electronics industry, epoxy resin is used in the production of insulators, motors, transformers and generators.
• Epoxy Resin for Painting Known as powder coatings, epoxy paint is found on many household goods like dryers, washers, stoves and similar white goods.
• Epoxy is also known for its corrosion prevention properties, making it an ideal solution to many household objects which may normally rust with time.
• Epoxy Resin have strong adhesive properties, many consumers use epoxy resin for the repair and maintenance of their household objects. Fragile items like glass, ceramic and china can be fixed quickly with an epoxy resin, helping secure broken or snapped items to the original piece.
