strain gauge adhesive

Kingmach's strain gauge adhesive portfolio includes quick-setting cyanoacrylates for instantaneous bonding in lab or field, and two-part epoxies that deliver the long-term stability needed for permanent structural monitoring. The cyanoacrylate adhesives generally bond within seconds and achieve full strength in minutes, making them suitable for rapid installations on clean metal surfaces. Epoxy-based variants offer a longer working time, allowing for precise gauge positioning on rough or porous substrates like concrete. Both types exhibit low creep under sustained load—a critical factor for strain measurement accuracy over months or years. Temperature performance is another aspect we emphasize; typical formulations maintain bond integrity from -40°C to +120°C, with specialized grades available for higher extremes. For outdoor applications, our adhesives resist moisture, oil, and mild chemical exposure, which helps prevent gauge detachment in harsh environments. We also supply complementary accessories: surface cleaning agents, gauge protection coatings, and application tools. All adhesives come with detailed technical notes and our engineering team can recommend the right product based on your sensor type, substrate material, and environmental conditions. Custom packaging sizes are available for bulk orders—something we frequently arrange for large-scale infrastructure projects. While the core chemistry is not unique, what sets Kingmach apart is the integration with our full geotechnical instrumentation range: when you buy strain gauges from us, you get adhesive that we've validated together, reducing compatibility guesswork.
