Unlike many other types of glues, an epoxy adhesive can fill gaps, and even be moulded into a structural part. Some makers claim in advertising that one can drill and tap their cured products and that they quickly cure "hard as steel" (as measured by Shore rating), though they are much weaker than steel in tensile strength and shear strength.
Curing is a chemical process employed in polymer chemistry and process engineering that produces the toughening or hardening of a polymer material by cross-linking of polymer chains. [1] Even if it is strongly associated with the production of thermosetting polymers , the term "curing" can be used for all the processes where a solid product is ...
J-B Weld epoxy is a two-part adhesive that can bond various surfaces and withstand high temperatures up to 500 °F (260 °C) constantly and 600 °F (316 °C) for short periods. It is water-resistant, petroleum/chemical-resistant, acid-resistant, and resists shock, vibration, and temperature fluctuations.
Epoxy encapsulation materials are a type of highly filled particulate polymer composite, comprising various components to meet the requirements for reliability, physical properties, and moldability. These components include silica , epoxy resin , hardeners, flame retardants , catalysts , and stress-relaxation additives .
Epoxy adhesives can be developed to suit almost any application. They can be used as adhesives for wood, metal, glass, stone, and some plastics. They can be made flexible or rigid, transparent or opaque/colored, fast setting or slow setting. Epoxy adhesives are better in heat and chemical resistance than other common adhesives.

The working time to make a bond, where the surface still retains sufficient tack, can range from seconds for fast-setting HMAs to infinity for pressure-sensitive adhesives. Set time Time to form a bond of acceptable strength. Tack The degree of surface stickiness of the adhesive; influences the strength of the bond between wetted surfaces.
