Master Bond EP3HT-LO is a single-component, non-premixed & frozen, heat-cured epoxy with an unlimited working life at room temperature.

Passes ASTM E595 tests for NASA low outgassing, making it well suited for use in the aerospace, electronic, microelectronic and optical industries. Features a lap shear strength of 1,600-1,800psi, a tensile strength of 5,000-6,000psi and a tensile modulus of 250,000-300,000psi. Withstands 1000 hr. of 85°C/85% RH exposure and features a dielectric constant of 3.9 at 60Hz and a volume resistivity of greater than 1014ohm-cm at room temperature. Withstands a variety of chemicals such as water, oils, fuels, acids and bases and is serviceable from -60°F to +400°F (-51°C to 204°C). Cures with heat, polymerizing in as little as 5-10 min. at 300°F (~150°C), and is said to bond well to metals, glass, composites, ceramics and many plastics.
