Silver filled epoxy adhesive has unlimited working life at room temperature
Master Bond Supreme 3HTS-80 is a one part, silver filled epoxy adhesive that is not premixed and frozen and features an unlimited working life at room temperature.

While typical heat activated epoxies require 120 to 177°C to cure, Supreme 3HTS-80 cures at 80 to 85°C within 2-3 hours, explains the company, making this system advantageous for bonding applications involving heat sensitive substrates. Supreme 3HTS-80 has a volume resistivity of less than 0.05 ohm-cm. Upon curing, it exhibits a hardness of 50-60 Shore D and a high thermal conductivity over 20-25 BTU•in/(ft2•hr•°F) [2.9-3.6 W/(m•K)]. This 100% reactive epoxy bonds well to metals, composites, glass, ceramics, and many plastics. As a toughened system, Supreme 3HTS-80 can withstand thermal cycling and shock with a service operating temperature range from -73°C to +177°C. The thick paste has a specific gravity of 3.9 that can be readily dispensed from a syringe.
