One Part, Fast Curing Epoxy Meets NASA Low Outgassing Specifications

EP3HT-LO features a good strength profile, with a lap shear strength of 1,600-1,800 psi, a tensile strength of 5,000-6,000 psi and a tensile modulus of 250,000-300,000 psi. It withstands 1000 hours of 85°C/85% RH exposure. This formulation offers reliable electrical insulation properties with a dielectric constant of 3.9 at 60 Hz and a volume resistivity of greater than 1014 ohm-cm, at room temperature. EP3HT-LO withstands a variety of chemicals such as water, oils, fuels, acids and bases. This high temperature resistant system is serviceable from -60°F to +400°F (-51°C to 204°C).

As a one-part compound, EP3HT-LO offers convenient handling and processing. It cures with heat, quickly polymerizing in as little as 5-10 minutes at 300°F (~ 150°C). This epoxy bonds well to metals, glass, composites, ceramics and many plastics. EP3HT-LO is available for use in ½ pints, pints, quarts, gallons and syringes. It has a shelf life of 6 months at ambient temperatures in original, unopened containers.
