EP40ND is a non-drip, toughened system with an easy to use 1:1 mix ratio by weight or volume. It may be used for bonding, sealing, and coating. EP40ND 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.
