5340 Epoxy
Thermally conductive, two-part epoxy packaged in 1:1 cartridges
A two-part epoxy, 5340 delivers ease of application and doesn’t settle during storage. The material features good dielectric properties, high lap-shear strength, and passes NASA outgas requirements. With its high lap-shear strength, 5340 Epoxy offers excellent adhesion, an important consideration for potting and bonding applications where keeping out moisture – and preventing potential delamination – is critical.
