Master Bond launches Master Bond EP40ND, 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.
Master Bond 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.
Adheres Well to Dissimilar Substrates
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. Master Bond 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.
Master Bond 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.
Master Bond 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.
