Industrial Epoxy Is a Structural Adhesive
Thermosetting Copolymer Adhesive Products
Industrial epoxy is a thermosetting copolymer; that is, it is formed from two different chemicals. It is formed from reaction of an epoxide or “resin” with a polyamine or “hardener”. Industrial epoxy adhesives are a major part of the class of adhesives called “structural adhesives”.
Industrial epoxies are known for their excellent adhesion, chemical and heat resistance, good-to-excellent mechanical properties and very good electrical insulating properties. These high-performance adhesives are used in the construction of aircraft, automobiles, bicycles, boats, golf clubs, skis, snowboards, surfboards and other applications where high strength bonds are required.
Two part epoxy adhesive coatings were developed for heavy duty service on metal substrates and use less energy than heat-cured powder coatings. Their low volatility and water cleanup makes them useful for factory cast iron, cast steel, cast aluminum applications and reduces exposure and flammability issues associated with solvent-borne coatings. They are usually used in industrial and automotive applications.
Epoxy resins are important in the electronics industry, and are employed in motors, generators, transformers, switchgear, bushings, and insulators. Epoxies are used in industrial tooling applications to produce molds, master models, laminates, castings, fixtures, and other industrial production aids.
There are hundreds of ways industrial epoxy products use can be modified and developed to suit most applications by adding mineral fillers (talc, silica, alumina, etc.), by adding flexibilizers, viscosity reducers, colorants, thickeners, accelerators, adhesion promoters, etc. This “plastic tooling” replaces metal, wood and other traditional materials; and they generally improve assembly efficiency, lower the overall cost and shorten the lead-time for many industrial processes.
