|Master Bond Unveils High-temperature Resistant Epoxy
Certified to meet ASTM E595 NASA low outgassing standards, Master Bond EP46HT-2AO Black is well suited for the aerospace, electronics, opto-electronic industries and can be used vacuum environments. This two component system
blends thermal stability with a high strength profile for a variety of bonding, sealing and encapsulation applications.
Properties of Master Bond EP46HT-2AO Black
- It combines superior thermal conductivity of 9-10 BTU•in/ft2•hr•°F [1.2981-1.4423 W/(m•K)] and reliable electrical insulation with a volume resistivity exceeding 1014 ohm-cm at room temperature.
- It has a glass transition temperature of 200-210°C and is serviceable over the wide temperature range of -100°F to +500°F [-73°C to +260°C].
- This dimensionally stable system delivers a tensile strength of 6,000-7,000 psi, compressive strength of 26,000-28,000 psi and tensile lap shear strength of 1,400-1,600 psi at 75°F.
- EP46HT-2AO Black also withstands a variety of chemicals including oils, water, acids, bases and fuels.
Epoxy Cures with Addition of Heat
Unlike most traditional two part epoxies
, EP46HT-2AO Black cures with the addition of heat, which allows it to have a working life of over 24 hours. It has a forgiving 100 to 30-35 mix ratio by weight and upon mixing; this thixotropic system has a viscosity of 140,000-280,000 cps. It bonds well to metals, composites, glass, ceramics, rubbers and many plastics.
is available in ½ pint, pint, quart, gallon and 5 gallon container kits. Part A of this system is black in color and Part B is gray. EP46HT-2AO Black has a minimum 6 month, maximum 1 year shelf life at ambient temperatures in original, unopened containers.
Master Bond Thermally Stable Adhesives
Master Bond EP46HT-2AO Black is thermally conductive and electrically insulative adhesive, sealant
and potting compound that meets NASA low outgassing requirements. This high strength, two component epoxy withstands temperatures up to +500°F.
