Master Bond has launched EP42-2LV Black, a two-part epoxy system with high resistance against harsh chemicals for bonding, sealing, coating and casting application. The system meets NASA’s low outgassing specifications and is serviceable over a wide temperature range from -60°F to 350°F.
EP42-2LV Black – Chemical Resistance with Easy-to-use Mix Ratio
EP42-2LV Black has low viscosity and can withstand immersion in acids, bases, solvents, fuels and oils. The epoxy system is recommended for applications in aerospace, electronic, optical and OEM (original equipment manufacturer) industries.
The epoxy system has 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 g batch.
Electrically Insulative Epoxy System with Long Working Life
EP42-2LV Black cures optically opaque at room temperature in two to three days or at elevated temperatures of 200°F in two to three hours. Master Bond recommends overnight cure schedule at room temperature followed by heat curing at 150-200°F for two to four hours for optimal performance.
The epoxy 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.
The long working life and lower exotherm, makes EP42-2LV Black suitable for larger potting and encapsulation applications. The epoxy system is available in half pint, pint, quart, and gallon kits.
