EP3UF-1 has a thermal conductivity of 9-10 BTU in/ft2 hr °F (1.30-1.44 W/(mK)), making it an effective thermal interface material. It contains a special filler with a small particle size. This allows it to be applied in bond lines as thin as 10-15 microns imparting a low thermal resistance of 5-7 x 10-6 K m2/W. It offers superior electrical insulation with a low dielectric constant of 4.5 at 60Hz as well as a high dielectric strength of 450 volts/mil (for 1/8” thick test specimen), both measured at 75°F.
As a single component system, EP3UF-1 is more convenient to handle, apply and store than typical two component adhesive systems. It has an unlimited working life at room temperature and cures in 20-30 minutes at 250°F, or in 10-15 minutes at 300°F. EP3UF-1 is available for use in ten and 30cc syringes, which are compatible with automated dispensing systems.
