Aremco-Bond 631


Aremco-Bondtm 631 is an advanced, two-part, modified epoxy system which exhibits exceptional mechanical, electrical and thermal properties. Its tensile shear strength is 3,000 psi as measured by ASTM D1002-94; volume resistivity and dielectric strength are 1.2 x 1014 ohm-cm and 440 volts per mil, respectively; and its maximum operating temperature is 400 oF (204 ºC). Aremco-Bondtm 631 is resistant to a wide variety of acids, bases, salts and organic fluids. Extended immersion studies have been conducted with no effect in various concentrations of hydrochloric acid, nitric acid, phosphoric acid, sulfuric acid, sodium chloride, ammonium hydroxide, sodium hydroxide, jet fuel, gasoline and toluene. Many other chemicals have been tested as well. Aremco-Bondtm 631 has also passed outgassing studies according to ASTM E-595. This feature is particularly useful for aerospace manufacturers that are interested in the outgassing properties of materials. The total mass loss (TML) at 125 ºC is 0.75%. The collected volatile condensable materials (CVCM) at 25 ºC is 0.35%. Aremco-Bondtm 631 mixes easily in a 1-to-1 ratio and cures at room temperature or by applying low heat. It is supplied in pint, quart and gallon containers as well as 50ml dual-barrel cartridges that can be loaded to mechanical or pneumatic guns for automatic mixing and dispensing.
