Overview of EP31
Master Bond EP31 is a two-component epoxy-based resin that is primarily designed for bonding applications. As with our other epoxy-based adhesives, it features high strength after curing. As shown by the case studies below, this compound can bond a variety of dissimilar substrate pairs, including aluminum-acrylic and Kevlar-polyimide. The case studies below provide illustrative examples of EP31 used to bond components of aeronautical wings (piezoelectric actuators), biological apparatuses (DNA amplification), and thermocouple housings.
Piezoelectric Microfiber Composite Actuators for Morphing Wings
Researchers from California State University at San Bernardino have developed two approaches for obtaining control surfaces. The authors explored a direct bonding approach in which microfiber composite (MFC) actuators were directly bonded to the Kevlar wing using Master Bond EP31.
Molecular Diagnostics in a Teacup
Researchers at the University of Hawaii at Manoa have developed a novel method based on loop-mediated isothermal amplification (LAMP) that does not require the use of such instruments to detect the presence of Salmonella DNA in milk. As part of this approach, Master Bond EP31 was used to bond the cylinders that housed the phase-change material (PCM) that was responsible for maintaining the reaction temperature of the device.
CO2 Flow System
Researchers at the University of California, Berkeley performed a variety of experimental and numerical investigations to determine the performance of supercritical CO2 to extract heat from porous rock for geothermal applications. Master Bond EP31 was critical to ensuring that the thermocouples measured the temperature without leaking supercritical CO2.
