Two-part epoxy displays 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 10-15μm. 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 2.88-3.60W/m·K, suitable for applications in the aerospace, optoelectronic and speciality OEM industries.
EP48TC has a tensile lap shear strength ranging from 900 to 1,100psi 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 offers a forgiving 100 to 40 mix ratio by weight, or 100 to 50 mix ratio by volume. The working life for a 100g batch at 24°C is 1.5-2h. The epoxy cures at room temperature or more quickly at elevated temperatures, and is serviceable over the temperature range of -173 to +149°C. The colour of Parts A and B is grey. EP48TC is available in standard packaging, ranging from half-pint to five gallon container kits.
