Structural Adhesives Industry Information
Structural adhesives are strong adhesives used for engineering applications, such as production of load bearing joints and composite-to-metal bonding. Generally, to qualify as structural, an adhesive must be able to withstand at least 1,000 psi in a lap shear test.
Structural adhesives are designed to remain uncompromised in the face of the most strenuous pressures, including those related to: chemical exposure, extreme temperatures, air pressure, rain, salt water, UV rays, shock, etc. This qualities allow them to perform a variety of tasks, such as: bonding assemblies, bonding surfaces, bonding parts, forming protective surface films, functioning as shim materials, producing load bearing joints, providing impact resistance and more.
Structural adhesives are important to customers in a wide variety of industries, including: aerospace, automotive, construction, industrial assembly, maintenance and repair, manufacturing, marine, metal processing and packaging and paper. To meet the needs of customers in these different industries, manufacturers can create structural adhesives with custom strengths, temperature resistances, appearances and more.
Typical structural adhesives include: phenolics, epoxies, polyurethanes, vinyl acetates, toughened acrylics, anaerobics and cyanoacrylates. Using structural adhesives such as these offers users a number of benefits, including: a wide range of flexibility and the elimination of costs associated with metalworking and metal finishing.
