Two-component epoxy with ultra low thermal resistance
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 5-7×10-6K"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 900-1100 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 75degF is 90-120 minutes. The epoxy cures at room temperature or more quickly at elevated temperatures. It is serviceable over the temperature range of -100degF to +300degF. The colour of Parts A and B is grey. EP48TC is available in standard packaging ranging from ½ pint to 5 gallon container kits.
Master Bond EP48TC is a two-component epoxy with high thermal conductivity that can be applied in very thin sections. Read more about Master Bond's liquid thermal interface materials at www.masterbond.com/properties/thermally-conductive-epoxy-adhesives.
