Epoxy resins are reactive polymers and prepolymers that contain epoxide groups. Epoxies react with themselves after catalysts or co-reactants like phenols and amines are added. Compared to other types of resins, cured epoxies have superior mechanical properties and chemical and thermal resistance. Their versatility means they are effective in varied applications, such as adhering structural components, electrical insulation, and coating concrete. Depending on the type of epoxy, it can be used on a variety of materials, including wood, metal, plastic, and stone.
Here is an overview of the different types of epoxy resins, their properties, the curing process, and their applications.
