- An epoxy coating is a coating compound consisting of two distinct elements: an epoxy resin and a polyamine hardener (also known as a catalyst). When mixed, the resin and hardener engage in a chemical reaction that creates cross-linking of the elements as it cures.

This sort of coating is popular in many different industries, but is often the most familiar when it comes to home appliances. Many refrigerators, washers, and dryers feature an outside coating of epoxy that gives then a finished shine and also helps them resist marks, scuffs, and other signs of wear. These sorts of coatings are often more aesthetic than anything, but in other settings the resincan also have a more important mechanical purpose. Electronics that are wrapped in coats of epoxy won’t overheat as easily, for instance, and when it comes to pipe insulation the technique can prevent leaks and can strengthen pipe walls against cracks from temperature changes and corrosive liquids.
There are a reasons why manufacturers and homeowners choose this sort of coating for so many different applications. It provides outstanding resistance to corrosive chemicals, heat, and ultra-violet light, for instance; it also exhibits excellent dimensional stability, extreme toughness, and abrasion resistance. In addition, it provides strong adhesion to a wide range of different surfaces, including glass, metals, fibers and numerous other modern materials.
Looking at things scientifically, an epoxy or polyepoxide coating is what is known as a “thermosetting copolymer.” It is a copolymer because it is formed from the combination of two different materials, namely an epoxide resin and a polyamine hardener. The hardener is effectively a catalyst that promotes polymerization. The polymerization process produces extensive cross-linking of the two materials contributing to the compound's strength. Epoxy coating is thermosetting because mixing the resin and hardener triggers polymerization, or curing, that generates heat. The polymerization process can be controlled by carefully varying the proportion of resin and hardener and the prevailing temperature. Some applications benefit from extended curing and high heat. The curing period can vary from minutes to hours or days.
Epoxy coatings and paints are frequently be divided into two broad categories: waterborne coatings and powder coatings. A waterborne epoxy coating is normally cured at ambient temperature. It is typically non-hazardous with low-flammability, facilitating transport and handling. The water base makes clean-up easier. An epoxy powder coating is usually cured under controlled, high temperature. This is often a common choice for coating the surface of white appliances, such as washers, dryers, refrigerators, and so on. It can also be used to seal things like warehouse floors or the undersides of boats or other small water craft. More sophisticated fusion bonded epoxy powder coatings are used to protect steel pipes from corrosion, particularly for water transmission. It is a high-performance material, the cost of which is usually justified in terms of an increase in the life of the equipment on which it is applied.
Getting the right finish with an epoxy resincan take a bit of patience, but it isn’t usually all that difficult. The hardest part is usually getting the proper consistency. Having appropriate tools is also really important in most cases. Prior to compounding, both the resin and hardener are liquids with low viscosityat room temperature and so can be easily handled. The quality of a finished product can vary significantly according to the precise proportions of resin and hardener used, however. Coatings are widely available in hardware and home improvement stores, but anyone who is unsure of how to complete their project would be wise to get a professional tutorial before beginning, and hiring an expert to do the job is often the safest course for any true beginner.
