One Part, Electrically Conductive Epoxy Meets NASA Low Outgassing Specifications

May 10, 2016

Master Bond EP3HTS-LO is a single component epoxy for demanding bonding, sealing and coating applications. This system passes ASTM E595 tests for NASA low outgassing, making it well suited for use in the aerospace, electronic, microelectronic and optical industries.

Featuring a silver filler, EP3HTS-LO is electrically conductive with a low volume resistivity of less than 0.001 ohm-cm. It also has a thermal conductivity of 12-15 BTU•in/(ft²•hr•°F) [1.73-2.16 W/(m·K)]. EP3HTS is dimensionally stable and bonds well to metals, glass, composites, ceramics and many plastics. It withstands a variety of chemicals such as water, oils, fuels and cleaning agents. This high temperature resistant system is serviceable over the wide temperature range of -60°F to +400°F.

As a one part compound, EP3HTS-LO offers convenient handling with no mixing and an unlimited working life at room temperature. This smooth thixotropic paste can be readily dispensed from a syringe. It polymerizes quickly at elevated temperatures with cure schedules of 45-50 minutes at 250°F or 20-30 minutes at 300°F.

EP3HTS-LO is available for use in glass jars and syringes. It has a minimum shelf life of 3 months and a maximum of 6 months at ambient temperatures in its original, unopened containers.
