Two Component Epoxy with Ultra Low Thermal Resistance and Superior Electrical Insulation Properties

April 7, 2015

Featuring special high thermal conductive fillers,  Master Bond EP48TC is two part epoxy paste that can be applied in bond lines as  thin as 10-15 microns. This material offers exceptionally low thermal  resistance of 5-7 x 10-6 K•m2/W, which imparts impressive  heat transfer capabilities and thermal conductivity of 20-25 BTU•in/ft2•hr•°F  [2.88-3.60  W/(m·K)]. It can be used in applications in the aerospace, electronic, optical,  specialty OEM and many other high-tech industries.

EP48TC has a tensile lap shear strength ranging from  900-1,100 psi and bonds well to a wide variety of substrates, including metals,  composites, glass, ceramics and many plastics. Even in thin sections, its  strength retention is outstanding. It also has a low coefficient of thermal  expansion, low shrinkage upon curing and excellent dimensional stability.

EP48TC has a forgiving 100 to 40 mix ratio by  weight, or 100 to 50 mix ratio by volume. The working life for a 100 gram batch  at 75°F is 90-120 minutes. The epoxy cures at room temperature or more quickly  at elevated temperatures. It is serviceable over the temperature range of -100°F  to +300°F. The color of Parts A and B is gray. EP48TC is available in standard  packaging ranging from ½ pint to 5 gallon container kits.
