epoxy paste

30 April 2015 | Master Bond Inc

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

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.
