Master Bond EP39MAOHT is a room temperature curing system for demanding bonding, sealing, coating, potting and encapsulation applications.

Viscosity and bonding

EP39MAOHT has a low mixed viscosity of 3.000-6.000 cps as well as a convenient one to one mix ratio by weight and a long working life of 120-150 minutes for a 100gram batch. This dimensionally stable system bonds well to a wide variety of substrates including metals, ceramics, composites and glass as well as many rubbers and plastics with very low shrinkage upon curing.

Performance properties and applications

This formulation features reliable thermal conductivity of 9-10 BTU•in/ft2•hr•°F [1.30-1.44 W/(m•K)], while retaining superior electrical insulation properties, including a volume resistivity of >1014 ohm-cm and a dielectric constant of 4.8 at 60 Hz. It offers chemical resistance to water, fuels and hydraulic fluids as well as many acids and bases. EP39MAOHT is serviceable from -100°F to +400°F. The combination of these performance properties makes it well suited for application in the aerospace, electronic, electrical, optical and specialty OEM industries.

Color and availability

EP39MAOHT is off-white in color and is available for use in 1/2 pint, pint, quart, gallon and 5gallon container kits.
