Toughened, non-drip epoxy meets NASA specs
Stephen Law
Electronics Production / Materials materials productionMASTER BOND EP40ND two component epoxy system is designed for bonding, sealing and coating applications. It is a non-drip, toughened system with an easy to use 1:1 mix ratio by weight or volume. Product meets NASA low outgassing specifications and has a high elongation of 80-90% at 75°F. It adheres well to many plastics, such as polycarbonates and acrylics, making it appropriate for applications that use substrates prone to stress cracking. The flexible system provides a low tensile modulus of 1,000-1,500 psi, and a relatively high lap shear strength of 1,600-1,800 psi. EP40ND has a Shore D Hardness measuring between 50-60 at 75°F. Serviceable from -100°F to +250°F, this electrically insulative compound can withstand rigorous thermal cycling, vibration, impact and shock.
