Toughened, Non-Drip Epoxy Meets NASA Low Outgassing Specifications

Master Bond EP40ND is a two component epoxy system, 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. 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.

This 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.

EP40ND cures within 2-3 days at room temperature, or faster with the addition of heat. The viscosity of Part A is 50,000-100,000 cps, Part B is a thixotropic paste. It has a long working life after mixing. In addition to plastics, this epoxy adheres well to a variety of dissimilar substrates such as metals, composites, glass, and ceramics. EP40ND can be used in aerospace, semiconductor, electronic, opto-electronic and medical device industries. It is available in standard packaging, as well as premixed and frozen syringes. It is also available in double barrel cartridges for use with a gun dispenser.
