It has volume resistivity over 1014 ohm-cm,  tensile strength over 12,000 psi, and tensile lap-shear strength over 2,000 psi.
Part A is clear and has 55,000 to 110,000-cps viscosity. Part B is amber and has a room-temperature viscosity of 75 to 130 cps. The parts mix at 100:30, and open time for a 100-gm mass at room temperature is 45 to 75 min. Cure is 3 to 4 hr at 150 to 200°F or overnight at room temperature followed by a 2 to 3-hr cure at 150 to 200°F.
