Epoxy Resin

Epoxy Resin

Epoxy refers to any of the basic components or cured end products of epoxy resins, as well as a colloquial name for the epoxide functional group.[1] Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups.

Epoxy resins may be reacted (cross-linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides), phenols, alcohols and thiols (usually called mercaptans). These co-reactants are often referred to as hardeners or curatives, and the cross-linking reaction is commonly referred to as curing.

Reaction of polyepoxides with themselves or with polyfunctional hardeners forms a thermosetting polymer, often with favorable mechanical properties and high thermal and chemical resistance. Epoxy has a wide range of applications, including metal coatings, use in electronics/electrical components/LEDs, high tension electrical insulators, paint brush manufacturing, fiber-reinforced plastic materials, and adhesives for structural and other purposes.

Epoxy resin  is Mainly used in chemical industry pipe , It is also suitable for electrical insulation materials, waterproof reinforcement, decorative coating, food container corrosion protection, chemical corrosion protection , adhesives coatings and composite materials such as those using carbon fiber and fiberglass reinforcements  although polyester, vinyl ester, and other thermosetting resins are also used for glass-reinforced plastic .
