Master Bond has launched EP62-1AO, an electrically insulated, thermally conductive two-part epoxy adhesive and sealant, featuring an exceptionally long working life of 12-14 hours at ambient temperature for a 100 g mass. The epoxy system is beneficial when bonding and sealing large or intricate parts that need time for mixing and applying.
Key Features of EP62-1AO Epoxy System
This material has a high strength profile with a tensile modulus of 600,000 to 650,000 psi and a tensile strength of 5,000 to 6,000 psi. The service temperature ranges from -60°F to +450°F and it offers a glass transition temperature of 120-125°C.
EP62-1AO has a thermal conductivity value of 9-10 BTU•in/(ft2•hr•°F), or 1.30-1.44 W/(m•K). Its chemical resistance profile is robust, especially when compared to other thermally conductive epoxies and can withstand a wide range of acids, bases and solvents. EP62-1AO has a low coefficient of thermal expansion of 18-21 x 10-6 in/in/°C.
Availability of Various Cure Schedules
The viscosity of the mixed compound is of a thixotropic paste consistency. There are several cure schedules options to choose from, all of which require a relatively low heat activation. Additional post curing for 2 to 4 hours at 200-300°F is recommended to obtain optimal performance properties. The sealant is available in 30 cc syringe kits, half pint kits, pint kits and quart kits.
