Epoxy is defined as a class of resin resulting from the polymerization of epoxides. They belong to a class of reactive prepolymers and polymers, which contain epoxide groups.
Epoxies usually contain two co-reactants, resins and hardeners, which when mixed, will chemically bond together. The end result of the chemical reaction is a strong and rigid thermosetting polymer with favorable mechanical and chemical properties.
Epoxy is also known as polyepoxide, epoxy resin, epoxy polymer, epoxy coating and epoxy paint.
Trenchlesspedia Explains Epoxy
Epoxy is widely used in many industries in a variety of applications including metal coatings, floor coatings, adhesives and in the manufacture of composite materials such as carbon fiber. The extensive industrial use of epoxies is mainly due to their extraordinary physical, mechanical and chemical properties such as thermal and chemical resistance, strong bond strength and durability.
In trenchless construction, epoxy resins are an essential component in the installation of cured-in-place pipe (CIPP) lining. The epoxy resin is applied to the interior of the pipelining which is then inverted (turned inside-out) such that the resin-saturated layer is in contact with the inner walls of the host pipe. The epoxy resin dries and hardens to form a permanent bond between the host pipe and the lining.
