This compound has an easy to use mix ratio of 100 to 40 by weight or 100 to 50 by volume with Part A being black and Part B being light amber. The viscosity of the mixed system is around 1,000-2,000 cps, and it has a long working life of 60 to 90 minutes per 100-gram batch. EP42-2LV Black cures optically opaque at room temperature in 2 to 3 days or at elevated temperatures of 200°F in 2 to 3 hours. For optimal performance, the recommended cure schedule is overnight at room temperature followed by heat curing at 150-200°F for 2 to 4 hours.
It meets NASA low outgassing specifications and is serviceable over a wide temperature range from -60°F to 350°F. This system is electrically insulative with a volume resistivity greater than 1014 ohm-cm and a dielectric constant of 4.0 at 60 Hz, at room temperature. These attributes, combined with its relatively long working life and lower exotherm, make EP42-2LV Black suitable for many larger potting and encapsulation applications.
EP42-2LV Black is recommended for applications in aerospace, electronic, optical and OEM industries. It is available in 1/2 pint, pint, quart, and gallon kits. Specialty packaging is also available in gun dispensers and premixed and frozen syringes.
