Potting and bonding electrical components
Understanding Epoxy Adhesives
Epoxy adhesives are part of the class of adhesives called "structural adhesives," which include
polyurethane, acrylic, cyanoacrylate and others. Epoxies are formulated as liquid reactive polymers that
undergo a chemical reaction when mixed and then cure to form a solid plastic material. Once the two
parts are mixed in their specified ratio, they begin the curing process and offer a limited working time
where the adhesive can be applied and the two surfaces positioned as needed. This work life lasts
anywhere from a few minutes to several hours. These structural adhesives provide high shear and peel
strengths, depending on the formula, and better heat and chemical resistance than other common
adhesives. In general, epoxy adhesives have the highest overall strength and offer the best performance
and most resistance to high temperatures, solvents and outdoor weathering.
Epoxy adhesive (often referred to as epoxy glue) is widely used in building and home construction;
aircraft and automobile manufacturing; bicycle, boat, golf clubs, ski and snowboard assembly as well as a
host of home use and other applications. It is used virtually anywhere high-strength bonds are needed
along with resistance to environmental conditions. These adhesives are popular for their ease of use,
mechanical strength and chemical resistance. Formulations can be created to make epoxy for plastic
flexible or epoxy for metal rigid, epoxy resin transparent or opaque, quick setting or slow setting. The
versatility with which these adhesives can be formulated helps meet almost any requirement for bonding
wood, metal, glass, stone and various plastics.
