Eliminate The Mixing, Keep The Properties

If you struggle with the time and cost of mixing separate adhesive components, one-component epoxies can make your life a lot easier. Yet many one-part epoxies trade off some physical properties for ease of use. That’s not the case with our 50–3122 One-Component Epoxy.

Even though it requires no mixing, 50–3122 does not skimp on strength, thermal, electrical and other important properties. Here’s a closer look at what this unique one-component epoxy offers:

  • Strength across a wide temperature range. With a tensile strength of 9,500 psi, a lap shear strength of 2,500 psi and a t-peel strength of 30 pli, 50–3122 creates exceptionally strong bonds. And it maintains its strength over a wide temperature range of –60 to 205°C, making it a good choice for structural bonding applications subject to temperature extremes.
  • Impact and vibration tolerance. 50–3122 also has a high tensile modulus of 675,000 psi, which helps it withstand heavy impact loads, vibration and thermal shocks.
  • Thermal and electrical insulation. 50–3122 is more than strong. It also acts as both a thermal and electrical insulator with a thermal conductivity of 1.44 W/m•K and a dielectric strength of 370 Volts/mil. These insulating properties come into play in many electrical, aerospace, appliance, automotive and industrial bonding applications.
  • Chemical resistance and low outgassing. Epoxies in general offer great chemical resistance, and 50–3122 is no exception. As a solvent-free formulation, 50–3122 also meets NASA outgassing standards (ASTM E595–07).

As with any one-part epoxy formulation, 50–3122 requires heat curing. To learn more about the recommended cure schedule and other technical specifications, download our 50–3122 Technical Bulletin.
