Epoxies are polymer materials that begin as liquids and are chemically changed into a solid. An epoxy based polymer is mechanically strong, chemically resistant to degradation of the chemical elements in the solid form and highly adhesive during conversion from liquid to solid. There are a wide range of basic epoxy chemicals from which an epoxy system can be formulated.

 

Physically epoxy systems contain two components, resins and a hardeners. The resin component is usually light, sometimes almost clear colored and almost odour free. Hardeners are usually dark and have a slight odor. When these two components are mixed, they will chemically and bond together and once the chemical reaction has finished, they will form a strong and rigid plastic material.

Applications of epoxy based materials are extensive and include coatings, adhesives and composite materials like carbon fiber and glass-reinforced plastic (although polyester, vinyl ester, and other thermosetting resins are also used for glass-reinforced plastic). Epoxies are known for their excellent adhesion, chemical and heat resistance, good to excellent mechanical properties and very good electrical insulating properties
